Switching folders currently keeps an active search applied and re-runs
it in the newly selected folder — deliberate behavior from #553, where
users wanted the query to follow them across folders. Others expect the
opposite: clicking Inbox/Sent should drop the search and just browse the
folder.
Add an opt-in setting (Settings → email behavior) that reconciles both.
Default is off, so #553's search-follows-you behavior is unchanged for
everyone. When on, any folder click clears the text query and advanced
filters and browses the folder instead of re-running the search.
Applied uniformly across the four folder-entry paths in MailApp — normal
mailboxes, per-account (Pro sidebar) folders, unified views, and cross
views — via one helper so no path diverges.
Adds Gmail-style horizontal swipe actions to message rows on touch
devices. Swiping a row past a threshold fires a configurable action and
snaps back; a coloured background with an icon is revealed under the
finger and grows when the release would commit.
- New `useSwipeActions` hook: claims a touch as a swipe only once the
horizontal travel dominates (vertical stays native list scrolling via
`touch-action: pan-y`, no preventDefault), resists past the commit
distance, and suppresses the tap that would otherwise follow.
- Two settings (Settings -> reading/email behavior): "Swipe right
action" (default Archive) and "Swipe left action" (default Delete),
each one of none / archive / delete / toggle read / toggle star /
spam. A direction set to an action the current folder does not expose
simply does nothing.
- Composes with the existing long-press (context menu) handlers; desktop
is unchanged (hover actions + right-click).
- Scoped to single-message rows; unit tests cover commit/short-drag/
no-action-side/vertical-scroll/tap-suppression.
Per review: gate the return-to-list behaviour behind a setting,
returnToListAfterAction, defaulting to true (the Gmail/Yahoo default). When off,
deleting the open message keeps the previous auto-advance-to-next behaviour.
Adds the setting to the store (persisted), a toggle under Reading settings, and
i18n keys across all locales (English; non-English need translation). The same
setting will govern mark-as-unread (#468).
