- Channel-row tags show only what's attached; a '+' opens a per-channel picker. Clicking a tag
filters the feed by it; a 'Your tags' sidebar widget makes that filter visible/clearable.
- Tag manager dialog (add/rename/delete; delete only confirms when the tag is in use), reachable
from the Channel manager and the feed sidebar; hovering a tag's count lists its channels, each a
link that focuses it in the Channel manager (DataTable gains an external filter input).
- Video cards get a reset action that clears all watch state (incl. an in-progress position).
- api.req() now raises the error dialog on 5xx and 400/409/422 with the server's reason.
- Add Last upload, total Length and a Normal/Shorts/Live breakdown, computed on read in the
existing grouped query (~35ms over the full catalog — measured, so no denormalization).
- Subscribers shown compact (919K), since the YouTube API already rounds them.
- Tag cell now shows only the tags actually attached to a channel; a '+' opens a per-channel
picker to attach/detach, instead of listing every user tag on every row.
Replace the stacked card rows with the reusable DataTable: sortable columns, in-header
Channel/Tags filters, status chips + page controls in one row, wider layout. Tag toggle
is now optimistic (no full refetch). Sync column collapses to one 'fully synced' chip;
Actions column carries hide/unsubscribe + a backfill control (admin reset / per-user
full-history opt-in). Channel status filter persists across reloads.
- Channel name: middle-click opens the channel's YouTube page in a new tab
(left-click still opens the in-app detail) plus an explicit external-link icon.
- recent/full sync badges show a check icon when the state is reached.
- New i18n key channels.row.openOnYouTube (HU/EN/DE).
The channel manager already styled the two deep-backfill-pending states
differently (solid clickable chip when you requested full history vs a faint
outline when another subscriber did), but both used the same "full history
queued" label, so a channel queued by someone else looked identical to one you
queued yourself. Give the by-other case its own label ("full history coming")
so the distinction is legible at a glance, not just on hover. Trilingual.
api: HttpError now carries the server's detail. Channels sync/backfill/unsubscribe
now detect a 403 (no YouTube grant) and show a 'connect your YouTube account'
message with a Connect action that opens the onboarding wizard, instead of a vague
'failed' toast. Translated HU/EN/DE.
Feed, VideoCard, Sidebar, PlayerModal, Channels, Stats, SettingsPanel,
OnboardingWizard, NotificationCenter, Toaster, ErrorBoundary and the relativeTime
helper are now fully translated in Hungarian, English and German, each with its own
locale area file (auto-loaded). Key parity verified across all three languages.
