 Watch later is **one collection**, deduplicated by YouTube video ID. Category lists are derived from the saved videos' channel identities and the **current** subscription categories: adding or removing a channel from a category changes its watch-later list after saving tags or reloading config with `r`. No category memberships are stored on individual videos.
 
-Browse a category with `c`, then use `W` for its watch-later list. From Search, Feed, or a channel view, `W` opens the combined collection. Watch-later views use saved title, creator, and publication metadata without fetching video lists, so they also work offline. Their filters are independent and retained during the session.

Their filters are independent and retained during the session; each pane's border title shows the active All, Unwatched, or Watched filter.
 
 Saved video titles are **magenta** in all video tables; categorized channel names remain cyan. A `✓` marks watched videos, including outside watch-later views. The selected row retains its usual highlight.
