[Feature] Group auto-generated playlists

[CarlosFdez]

Eole theme is pretty neato, although currently it seems that auto-generated playlists are just lumped in with the regular playlists. It'd be nice if these auto-generated playlists were either hidden, grouped together at the top under the Create Playlist button (with dividers), or in a new sub-panel anchored to the bottom (with the middle section being scrollable).

If this is something you'd be down for but don't have time to do, if a solution has your blessing, it'd be nice to say which one in case someone wants to tackle it. Like me if I find some time.

So far I've identified Library Selection and Library Playback as forcefully injected, and then via interaction I've gained Library Viewer Selection and #Quicksearch [Blah].
