# Post-0.1.0 usability backlog

Status: **open, expandable by design.** This document is not a fixed release
plan. It collects items found by actually using qtmaildir after 0.1.0, and it
grows as more turn up. Nothing here is scheduled; picking what ships in a given
release is a separate decision.

Source: usage notes taken while running the app, 2026-08-03.

**Numbers here are this document's own.** The user's own notes were numbered
independently and the two sequences drifted apart once items were split: what
those notes called 12 is item 13 here, and item 14 here (the tag column) was
never in them at all. Items 15 to 17 come from a later pass over the same
notes. Cite these numbers, not the notes', and do not renumber to reconcile.

**The notes are the upstream source and they keep growing.** The user adds to
them while using the app, so this document goes stale on its own. Items 28 to 35
came from one such pass on 2026-08-04 and included two defects that had gone
unrecorded here for a while. Items 39 to 45 came from the 2026-08-05 pass, which
found one more defect (41, a message body silently dropped by the MIME walk) and
one item that cannot be planned at all until the user says where the thing it
manages lives (44). Compare the two at the start of a session; the procedure is
in `CLAUDE.md`.

Numbering is stable. New items append with the next free number and never
renumber, so a note referring to "item 7" keeps meaning the same thing. An item
that is dropped stays in the table marked `dropped` with a one-line reason.

**The status table below is the index of every item; the sections are only the
open ones.** Item 73 moved the done, dropped and postponed sections out to
`2026-08-03-post-0.1.0-usability-closed.md`, which took this file from just over
five thousand lines to under six hundred. Nothing was deleted and nothing was
renumbered: a closed item keeps its row here, with its date and outcome, and its
full Observed/Cause/Approach section is in that file under the same number. Look
there when a row cites evidence you need.

**Items 20 and 53 are both on master since 2026-08-10**, as the card list. Item
20's original presentation, the one the user rejected on sight, is preserved on
the branch `item-20-message-rows` at 029a50e and was never merged; the branch
`card-list` carries the work that was. Any file or line reference in item 20's
entry, now in the closed-items file, points at that PARKED branch, not at
master, where the same lines are unrelated. Item 53 records why the first
attempt was rejected and is worth reading before changing the thread pane again.

## Theme

0.1.0 was built to a spec written by someone who lives in neomutt. The result
is a keyboard-driven reader with almost no visible affordances. The notes below
are, with few exceptions, one complaint restated in several forms: **the app
does not tell the user what it can do, and it does not remember what the user
told it.** Two clusters follow from that:

- **Persistence.** Splitter position, font size, window geometry, and the
  account selection all reset on restart. Each is small on its own and
  aggravating every single launch.
- **Discoverability.** Shortcuts are the only route to most actions, and there
  is no menu bar, no toolbar, and no way to see the key bindings from inside
  the app.

Both clusters are cheap to fix. Neither was an oversight in design so much as a
consequence of specifying the app as "a GUI counterpart to neomutt" and then
taking that too literally.

Sizes are rough: XS under an hour, S a sitting, M a session.

## 21. Default shortcuts are not sensible enough

**Observed (user, 2026-08-04):** "improve the default shortcuts to some sensed
defaults."

**Unspecified in detail**, so ask which bindings feel wrong before proposing a
table. What is worth recording is the history, because the defaults have
already moved once and the reasons still constrain any second pass.

**Where the current defaults came from.** 0.1.0 used bare letters. They were
replaced in the 0.2.0 menu work for two reasons that have not gone away: a
single letter cannot be a menu accelerator without claiming that letter
window-wide, and a bare capital such as `N` parses to an unshifted `Key_N`,
which no keystroke emits, so `toggle_unread`, `flag` and `sync` were dead keys
that appeared to be bound. See `KeyMap::defaultBindings()` and
`normalizeSequence()`.

**Constraints on any new default.**

- **Do not test reachability with synthetic input.** `QTest::keyClick()` does
  not reproduce a keyboard layout: it reported `Ctrl++` as dead when it is
  exactly what the `+` key emits on the user's Italian layout. Verify against
  the real keyboard, as `CLAUDE.md` records.
- Every binding is overridable in `[keys]`, so this is about what a fresh
  install feels like, not about what is possible.
- `Return` is a special case already resolved: it belongs to `open_thread` but
  the query bar claims it back while focused, so a proposal that moves it must
  not resurrect that bug.

## 22. Translatability audit and i18n wiring

**Observed (user, 2026-08-04):** "a full check of the codebase and wiring up of
the i18n system."

**This is a debt `CLAUDE.md` already records.** The rule that every user-facing
string must be wrapped in `tr()` was added while building query completion, and
that file states plainly that "pre-existing code has not been audited against
this rule". This item is that audit, plus the loading machinery which does not
exist at all.

**Two halves, and they are different sizes.**

- *The audit.* Every user-visible string in `src/` checked for `tr()`, with the
  translation context correct: a string in a free function needs
  `Q_DECLARE_TR_FUNCTIONS`, since calling `QObject::tr()` compiles but files it
  under the wrong context. `lupdate` output is the evidence here, not reading.
- *The wiring.* Nothing loads a `.qm` file today: there is no `QTranslator` in
  `main.cpp`, no `.ts` files in the tree, and no CMake rule to build or install
  them. Until that exists, a translated string has nowhere to come from.

**Constraint:** query syntax is not user-facing text. notmuch keywords such as
`tag:` and `date:` are wire format and must never be translated, only the prose
describing them. The completion vocabulary is exactly this trap: the values are
literal, the descriptions are prose.

**Verification:** run `lupdate` and read the generated `.ts`. A string that
does not appear there is not translatable, whatever the source looks like.

**No longer on demand.** The entry said to do this when a defect needs it, not
before (user, 2026-08-04). Item 66 needs it now, so the deliverable is a RED
reproduction of that defect, not fixture wiring on its own. Fixing 66 is
deliberately excluded: it has never been isolated, and designing a fix beside a
hypothesis is how a wrong one gets locked in.

**Smaller than this entry has read since 2026-08-04.** No hook has to be added
to `MainWindow`. `wireWorker()` (`src/mainwindow.cpp:1440`) already builds the
worker from `m_config.notmuchConfig()`, an ordinary config key, so a test that
writes a `qtmaildir.conf` pointing at the fixture gets a real worker through the
shipping path with nothing in `src/` changed. Mind the `[general]` prefix trap
when writing that file.

## 40. No live filter over the current view

**Observed (user, 2026-08-05):** "search in current view", spelled out as two
things: "a light filter applied live on the current view", and "a search bar
appearing as soon as we type while no entry box is focused".

**Cause (verified in code):** the only search is the query bar, which runs a
notmuch query and replaces the result set. There is no client-side filtering
of an existing result: no `QSortFilterProxyModel` anywhere in `src/`, and
`ThreadListModel` has no filter of its own. Narrowing the current view therefore
means writing a new notmuch query and losing the view.

**Approach.** Distinct from the query bar, and the distinction is the point: this
filters rows already fetched, without touching notmuch.

- A filter over the model's loaded rows, matching subject and from, case
  insensitively. No worker round trip.
- A filter strip that appears on the first keystroke while no entry box has
  focus, and disappears on Escape, restoring the full result set.

**Constraints.**

- **Type-to-filter competes with the plain-letter shortcuts.** Item 3's outcome
  records that a plain-letter `QAction` shortcut is suppressed only while an
  editable widget has focus, which is exactly the state this feature does not
  start in. Any binding that is a bare letter would be swallowed by the filter
  strip or would swallow it. Check the current defaults before choosing the
  trigger, and prefer appearing only for characters no action claims.
- Escape already blanks the message pane (item 32). If Escape also closes the
  filter, decide the precedence explicitly rather than letting whichever handler
  runs first win.
- The filter is presentation only: it must not clear the selection, the undo
  stack, or the query, and the pending-edit count must not move.
- Interaction with item 39: a filter and a sort over the same rows want the same
  proxy. Whichever is built first should leave room for the other.

## 65. No full code review and optimization pass

**Observed (user, from the notes):** "full code review and optimization."

**Cause:** not a defect. The codebase has grown from the 0.1.0 spec through
sixty-odd backlog items, and nothing has gone back over it as a whole.

**Why this cannot be planned from the backlog.** "Review and optimize" names no
symptom, no measurement and no target. There is no reported slowness to chase,
and the one performance property the design does commit to (threads emitted in
batches of 200 so a 10k-thread query paints immediately) already holds. An
optimization pass with no measurement behind it is the kind of work that
produces a large diff and no change a user can notice.

**What it needs before it can be sized.** The user saying which of these they
meant: a correctness/security review of a named area, a specific operation that
feels slow with the query that makes it slow, a dead-code and duplication sweep,
or the translatability audit that is already item 22. The first three are
different pieces of work with different sizes, and the fourth is already
recorded.

**Size: `?`, unspecified.** Do not propose a design for this; ask.

## 66. Selecting a thread root leaves the message pane blank until a reply has been selected

**Observed (user, from the notes):** clicking the main message of a thread shows
nothing in the right pane. After expanding the thread and selecting a reply,
clicking the main message again renders it correctly. The user filed a second
observation as a possible duplicate: clicking the main message shows the whole
thread with stubs and the last two replies expanded, and after clicking a reply
and going back to the root, only the root's own message is shown.

**Cause (partly verified, and the two halves are not the same fault).**

The second half is not a defect at all. A thread row renders the conversation and
a message row renders one message; `onThreadSelected` (`src/mainwindow.cpp:1847`)
branches on `isMessageRow` for exactly that. What breaks the user's expectation is
that going back to the root should return to the conversation view, and it does
not always: `m_currentMessageId` is set by the message branch
(`src/mainwindow.cpp:1860`) and `onMessageLoaded` refuses to render when it is
empty (`src/mainwindow.cpp:1924`), so the two paths are ordered by which reply
lands first, not by which row is current. This is the "a queued load can outlive
the state that started it" class already recorded in CLAUDE.md.

The first half, a blank pane on the very first click, has a candidate and only a
candidate: `onThreadSelected` returns without loading anything when the index is
not yet selected (`src/mainwindow.cpp:1804`), a guard added so that a view taking
focus does not open and mark-read a message the user never looked at. If a click
can deliver `currentRowChanged` before the selection model is updated, which
CLAUDE.md records as this signal's documented behaviour, that guard drops the
load and `onSelectionChanged` only reloads when the row CHANGED
(`src/mainwindow.cpp:1721`), which it did not.

**Approach:** do not fix from this reading. The candidate above is exactly the
kind of plausible cause the project has been burned by twice; instrument the
running application and watch the order of `currentRowChanged`,
`selectionChanged` and the worker reply for one first click on a cold view.

**Ruled out 2026-08-14: the simple case does not reproduce.** Item 36 shipped
the fixture this entry said was missing, and
`selectingAThreadRootShowsItInTheMessagePane` in `test_mainwindow` now builds a
real database, runs a real query and selects an unexpanded thread root with a
real `threadLoaded` arriving. The pane renders. The test is mutation-confirmed
to fail when `onThreadLoaded()` is disabled, so it is a probe with teeth rather
than a green that proves nothing.

**What that leaves, and it sharpens this entry's own candidate.** The test uses
`setCurrentIndex()`, which updates the selection model SYNCHRONOUSLY. A real
mouse click does not, and the guard at `src/mainwindow.cpp:1804` returns without
loading when the index is not yet selected. So the negative result is consistent
with the candidate above rather than against it: it says the defect is in the
CLICK path, not in the load path. Reproducing it needs `QTest::mouseClick` on
the viewport at the row's `visualRect`, not a programmatic selection.

Two other conditions remain unexcluded and are cheaper to try than a click
harness: a thread of more than two messages, and a cold page cache, which item
74 measures as seconds on this machine and which is exactly the window in which
an ordering fault would show.

**Constraints:** the mark-read guard at 1804 must survive whatever is done, it is
item 35b's fix and removing it re-opens marking mail read without the user having
seen it. A fix that only re-orders the two guards will look correct and will still
be timing-dependent.

**Size: S**, and a defect rather than an enhancement.

## 68. A forwarded subject gets no `passed` tag

**Observed (user, from the notes):** "passed tag should appear when subject is
`Fwd:` and `Fw:`." Refined in session on 2026-08-11: the user had noticed
`passed` appearing on messages whose subject carried `Fwd:` and not on `Fw:`,
and asked to expand the rule to both.

**Cause:** there is no rule to expand. `passed` is the Maildir `P` flag in the
message filename, translated into a tag by notmuch because
`maildir.synchronize_flags=true`. The flag is written by whichever client
forwarded the message, or by the server over IMAP; nothing reads a subject line
anywhere in the chain. qtmaildir only ever colours the tag
(`src/tagcolors.cpp:36-37`) and the database's `post-new` hook does not mention
it either.

**Measured against the real database (2026-08-11):**

| Query | Count |
|---|---|
| `tag:passed` | 6 |
| `tag:passed and subject:"Fwd:"` | 1 |
| `tag:passed and subject:"Fw:"` | 0 |
| `subject:"Fwd:" and not tag:passed` | 194 |
| `subject:"Fw:" and not tag:passed` | 28 |

Six tagged messages in the whole database, and every one of them carries `P` in
its filename flags. The single overlap with `Fwd:` is a message that was
forwarded and whose subject was already a forward, not evidence of a rule: 194
`Fwd:` subjects carry no tag at all. The correlation the observation rests on
does not exist.

**Approach and the decision it needs first.** Two different features, and the
measurements above decide how far apart they are.

*Display only.* The card shows a forwarded mark when the subject matches. Touches
no mail, changes no flag, reversible by deleting the rule. XS.

*Write the tag.* qtmaildir sets `P` from a subject heuristic. With
`maildir.synchronize_flags=true` that flag is a filename change that mbsync
carries out to the server, on 222 existing messages, on a guess about a string.
Not cleanly undoable, and it asserts a meaning for a flag this application did
not define. Recommended against; recorded so the choice is deliberate rather than
forgotten.

**Constraints:** localised clients use their own prefixes, and `Fwd:` can appear
inside a subject rather than at its head, so whatever matches must be anchored.
If the tag is ever written, it must not be re-applied on every sync in a way that
produces pending edits the user never made, item 28 is the record of a count
going wrong. The display-only route avoids that entirely, since it derives the
mark at paint time and stores nothing.

**Size: S** as written, XS if it is display only. Most of it is the decision, not
the code.

**Status:** left open deliberately on 2026-08-11. The cause is settled and the
options are costed; the user has not chosen, and no code was written.

## 72. No khard/khal integration

**Observed (user, from the notes):** "investigate khard/khal integration (light
PIM, probably worthy after we add send capabilities)."

**Cause:** not a defect. v1 is read-and-organize; there is no address book and no
calendar anywhere in the codebase.

**Why this cannot be planned.** The user's own note places it after send, and
send is v2. What "integration" means is undecided: completing recipients from
khard when composing, showing a sender's card, or acting on an invitation.
Those are three different features.

**Size: `?`, unspecified**, and out of scope until v2 exists. Ask before designing
anything.

## 74. The first query after boot sits on "Searching..." for seconds

**Observed (user, 2026-08-11):** the first start of the day takes noticeably
longer to show its default view, and the delay happens while the status bar
reads "Searching...".

**Cause: the notmuch index paging in from disk, not this application's code.**
Measured by instrumenting `main()`, the `MainWindow` constructor and
`NotmuchWorker::runQuery` behind an environment variable, then running the same
`tag:inbox` query (4444 threads) warm and again after evicting the index from
the page cache with `posix_fadvise(POSIX_FADV_DONTNEED)`:

| phase | warm | cold |
|---|---|---|
| `notmuch_query_search_threads` returns | 0 ms | 411 ms |
| first batch of 200 reaches the model | 10 ms | 642 ms |
| walk complete, all 4444 threads | 154 ms | 5714 ms |

A 37x difference over the identical code path. The index measured 1.1 GB. The
in-process startup costs nothing by comparison: `QApplication` in 20 ms, the
whole `MainWindow` constructor in ~120 ms, and the window is shown and
interactive at ~196 ms in both the warm and the cold run.

**There is nothing to fix in the query path**, and the measurement exists mainly
so this is not re-investigated. Two things it did establish that are worth
keeping. The default startup view is whichever saved query `startup_query` names,
defaulting to `Unread`, so a user with an empty unread view never sees this at
all and a user whose default is Inbox always does. And batching already works:
rows land from 642 ms cold, long before the 5714 ms finish.

**The one real defect it exposed is the status bar.** "Searching..." is set once
in `runQuery` and cleared only on `queryFinished`, so it keeps claiming the
query is running for the full 5.7 s while rows are visibly arriving behind it.
That makes a slow query read as a frozen one. The fix is to update the text per
batch with the count so far rather than holding one string, which changes no
timing and only stops the bar from lying.

**The user declined this on 2026-08-11**, having asked for the explanation
rather than a change. Recorded as open because the status bar is still
inaccurate, not because anything is expected to happen.

**Size: XS** for the status bar. The cold-cache cost itself is not addressable
here and should not be attempted: prefaulting 1.1 GB at startup to make one
query look fast is a worse trade than the wait.

## 78. No way to build a rule from something visible in a message

**Observed.** The user would like to select an address or another piece of a
message in the main window, right-click, and be offered a rule built from it.

**Cause.** Not a defect, unbuilt.

**Narrowed 2026-08-14, and most of the work is already done.** The search half
shipped as item 85, which is the road a rule is made from: search for a value,
save the query, create a rule from the saved query. What remains here is a
SHORTCUT across that road, and both of its halves now exist.

- The menus are built and every surface already extracts its value as a
  finished query (`SearchOffer`, `src/searchterm.h`). A rule entry is another
  action beside the two search ones, not new plumbing.
- The seeded-dialog path exists from item 81:
  `MainWindow::showTagRulesDialog(const TagRule &seed)`. A rule from a message
  becomes a second caller of it, with a different seed, which is what item 81's
  spec anticipated when it made the seed a whole `TagRule` rather than a query
  string.

**Approach.** Decide it after using item 85 for a while. Which values are worth
promoting straight to a rule is a usage question, and the earlier answer to it
was wrong (see below), so it is worth having the evidence first.

**Constraints.** The original approach here said to start from the thread
list's context menu "where the sender is already a value the model holds".
**That is false and item 85 verified it.** `ThreadSummary::authors` comes from
`notmuch_thread_get_authors` and is a DISPLAY SUMMARY, reading `Alice, Bob` or
`Alice| Bob`, so a `from:` built from it matches nothing. A real address comes
from `MessageNode::from` or `ParsedMessage::from`, neither of which the thread
list carries. Any thread-list entry needs an address resolved from a message
first.

JavaScript is disabled in the profile and must stay disabled. Item 85 reads a
body selection with `QWebEnginePage::selectedText()`, which injects no script;
reuse that rather than adding anything.

The rules file is shared with mailctl, so a rule created here must go through
`TagRules` and preserve unknown fields; see "Changing the shared rule format"
in CLAUDE.md.

**Size: S**, down from M now that item 85 has built the menus and item 81 the
seeded dialog.

## Deferred, unsized, or split out

Items noted while triaging but not part of the original list. Same numbering
sequence, appended as they arise.

| # | Item | Why here |
|---|------|----------|
| 12 | `HtmlBuilder` CSS is light-theme only | **Done 2026-08-07**, and moved to the main status table. Kept listed here so the split from item 5 stays traceable. |

## Adding to this document

Append a row to the status table with the next free number, then a section using
the same shape: **Observed** (what the user saw), **Cause** (the code, with file
and line, verified not assumed), **Approach**, **Constraints**, and
**Verification** where it is not obvious. Do not renumber. Do not delete: mark
`dropped` with a reason.

**When an item closes, move its section to
`2026-08-03-post-0.1.0-usability-closed.md`** and leave the status table row
here with its date and outcome. This is what keeps the file readable, and it is
the step that was missing for seventy items: doing it only once, as item 73 did,
buys a few months and then the problem returns. Move the section on the commit
that closes the item, not in a later cleanup pass. Where the closed section
records a trap that is still true of the code, that trap belongs in `CLAUDE.md`,
which is where it will actually be read.

**A fully specified item goes in its own file under `docs/superpowers/specs/`,
not inline here.** This document is a backlog: its job is to say what is open,
how big it is, and what decides whether it can be picked up. A design that runs
to a hundred lines buries that under itself.

The split is by depth, not by size on the day. An entry stays here while it
records an observation, a cause and an approach. It moves out once it carries
decisions the user made, measured evidence, and constraints that have to be read
before writing code. Items 53 and 63 are the pattern: the entry keeps the
finding and the size, and points at the spec with one line saying to read that
instead. Carry the two or three constraints a reader needs in order to decide
whether to open the spec at all, and leave the rest there.

Name the spec `<date>-<name>-design.md`, and state in its header which backlog
items it resolves, so the numbering stays traceable in both directions.
