 The collection is persisted independently in `saved-videos.toml` beside `config.toml`, using the same atomic, owner-only writes and validation as watch later. Saving repeatedly does not add duplicates. Configure saving and the collection selector with `video.saved.save` and `view.saved.browse`; direct category browsing uses `view.saved.category`. The corresponding watch-later navigation actions are `view.watch_later.browse` and `view.watch_later.category`. Selectors use the shared `selector.*` and `input.*` bindings. The live hints and `?` reference reflect overrides. Alt shortcuts require the terminal to transmit Alt/Meta; if macOS Option inserts symbols, enable Option-as-Meta or remap the actions.
 
+## Currently watching
+
+`C` opens one combined, offline list of started but unfinished videos. It uses the shared temporary tab and back/forward navigation; configure the shortcut with `view.watching.browse`.
+
+A validated, acknowledged **positive playback position** adds the video—not merely launching Terebi or receiving position zero. Reaching the existing eligible **95% watched threshold** automatically removes it. Already-watched videos never enter. Unknown-duration or ineligible playback can appear but stays unfinished unless a later eligible report marks it watched or you remove it.
+
+Entries and their title/creator/publication metadata survive restarts. Reports written while Tubular is closed are recovered on the next launch. Older sessions without video snapshots can populate the list when matching watch-later/saved metadata exists; otherwise they continue updating watched status without inventing missing metadata.
+
+Use `x` for individual removal or `X` for bulk confirmation. Removal neither marks the video watched nor changes watch later/saved videos. Continued reports from existing sessions cannot re-add a removed entry, including after restart; deliberately starting a new session can re-add it if still unfinished.

 ## Collection removal
 
-Removal controls apply **only in watch-later and saved-video views**, including previews opened from those lists. Search, Feed, ordinary channel/category views, and their previews do not expose removal actions or hints. Text fields and selectors retain their normal controls.

-`x` immediately removes only the selected video from the active collection. `X` snapshots the current list and opens bulk confirmation: watch later uses the current category and All/Unwatched/Watched filter; saved videos uses the current category's entire saved list. An empty list does not open confirmation.
