  // X view playback history (?)

  //   - support dynamic (on-demand) playlists
  // - support input text box for adding to playlist (how to handle title?)

  // X option (probably a button) to add current page (url, title) to playlist
  //   X align with addLinkToPlaylist in background.js (no repeated videos)
  // X button to add channel to youtube page (copy gql mutation to clipboard) (like the automa version)

  // X add personal rating feature ("enjoyed", "this was important", etc)
  // - option to move video (including status) to another playlist
