How about playlists and history, though? Personally I don't use subscriptions, and have no use for them. I suppose and app like this could provide a third party (self host able api) account service - recording history and managing/syncing playlists? Maybe with an option to merge in entries from Google account playlists from time to time? Playlists are nice not just for playing/listening, but also downloading for offline use/backup/archive. Ed: i see that it has local history and playlists, with option to export data - but apparently no option to load data (whether from youtube/Google or an earlier export).
