A new in-app toast surface is the batch's spine, making the silent-failure and
global-status gaps fixable:
- Toast infra: store/toasts.ts (useToasts + toast(); auto-dismiss) + ui/Toaster.tsx
(non-portal bottom-center stack, avoids the Fluent-portal GPU flicker). Unit-
tested (test/toasts.test.ts). Mounted at the app root beside LiveRegion.
- UX6: shared renderer reveal.ts revealFile('open'|'folder') awaits the IPC result
and toasts the main-process reason instead of silently no-oping on a moved/typed-
out file. safeShowInFolder upgraded to return an error string like safeOpenPath
(preload/mock/Api types updated).
- UX9 / UI25: a Fluent CounterBadge on the sidebar Downloads nav item shows the
active (downloading + queued) count from any tab, via a count-only App selector
that doesn't re-render on progress ticks.
- UX15: cancelAll store action + a "Cancel all (N)" header button.
- UX24: the disabled "Check watched" button uses disabledFocusable + a Hint that
explains it needs a watched source.
- UX12: the Terminal gate gains an inline "Enable custom commands" button, so it's
no longer a dead-end pointing at another screen.
- L144: the DownloadBar duplicate guard now also checks history — a URL downloaded
earlier warns "Already downloaded: …" (dupInHistory) vs "Already in your queue: …".
Deferred with rationale (CODE-AUDIT.md): UX7/UX8 (Settings IA redesign — visual),
UX18/UX26 (subjective/visual polish), L131 (arguably by-design, needs live taskbar),
L142 (history/templates/sources IPC-return reconciliation — a focused own PR).
Verified: typecheck (node+web) + 279 tests + eslint + production build green;
touched files prettier-clean.

Phase A of the Seal feature-parity roadmap: configurable post-processing via a
shared DownloadOptions model (src/shared/ipc.ts), editable as persisted defaults
in Settings and overridable per-download in the download bar.
- audio formats (mp3/m4a/opus/flac/wav/aac), video container (mp4/mkv/webm),
preferred-codec sort (-S vcodec)
- subtitles (download/embed/langs/auto), SponsorBlock (remove/mark + categories
+ force-keyframes-at-cuts), embed chapters/metadata/thumbnail, square-crop
audio artwork
- playlist downloads: probe via `-J --flat-playlist`, inline selection UI
(checkbox list, select-all/none, live count); each entry enqueued as its own
single-video download, reusing the existing queue/concurrency/history
- reusable DownloadOptionsForm shared by Settings and the download bar so the
defaults and per-download override never drift
- ROADMAP.md tracking full Seal parity (phases A-E)
Also includes in-tree security hardening that landed alongside: preload sandbox
(CJS preload output), http(s)-only window-open + blocked renderer navigation,
argv-injection guard for URLs (src/main/url.ts), extension-allowlisted file
open/reveal (src/main/reveal.ts), yt-dlp version-check timeout, and a minimal
window.electron presence marker.
