The full page

The ⤢ icon at the top of the panel opens Matinee in its own tab:

• Home: what you were watching, what's waiting to be sorted, a forgotten gem, your folders.
• A sidebar of folders, smart views and tags (drop a dragged video on any folder), a grid of videos, and the details of the one you pick: Watch, Edit, its moments, its note.
• Export a folder or view as Markdown or CSV, or copy it as a YouTube playlist link (YouTube takes 50 videos per link).
• Back to YouTube returns to your YouTube tab. Dragging the side panel wider also shows a video's details beside the list.
