Per user feedback: promote Plex from a hidden feed-Source option to a first-class
left-nav module, with its own filter sidebar and the shared top search box.
- Plex is now a nav-rail module (page='plex', gated on me.plex_enabled) — its own
page → correct browser Back/Forward; removed the Feed Source-dropdown 'plex' hack.
- PlexSidebar.tsx: left filter column (library scope, watch-state for movies:
all/unwatched/in_progress/watched, sort) — per-account persisted (App state).
- Header search box now also serves the Plex page (integrated search); the live
YouTube-search escalation stays feed-only.
- PlexBrowse.tsx reworked: infinite scroll (IntersectionObserver, no 'Load more'),
content-visibility for smoother long-list scroll, show drill-down rides history
(useHistorySubview) so Back returns to the grid; dropped the stray 'YouTube feed'
button on the show page.
- backend /browse gains a per-user watch-state filter (show=, movies only).
- plex i18n (navLabel + filter.*) en/hu/de.
Note: episode-title 'Episode N' on some shows (e.g. Westworld) is Plex-side
(unmatched show) — we mirror what Plex has; Match/Refresh in Plex + re-sync fixes it.
- app/plex/sync.py: full reconcile of enabled movie/show sections into plex_*
(upsert by rating_key). Reuses Plex's own codec info to classify browser
playability (direct/remux/transcode) — no ffprobe. Movies + episodes become
playable leaves; shows/seasons mirrored for the drill-down.
- routes/plex.py: GET /libraries, /browse (FTS search + sort + paging, movie
leaves or show cards), /show/{rk} (seasons+episodes, per-user state), /image
(proxies Plex art, no duplication); admin POST /sync. All auth'd, demo-allowed.
- scheduler: plex_sync job (interval settings.plex_sync_interval_min).
- Verified against the real server: 2 libs, 3206 movies, 260 shows/961 seasons/
14768 episodes synced in 13s; FTS search + drill-down work. Playability:
~1% direct, 89% remux, 6% transcode (informs P2/P3).
