Playlist filtering

[gurutech]

Similar to other requests where if you have multiple media folders configured, but choose only one from the dropdown on the left margin, only the albums from that folder/subfolders will show up under the "Home" section....

Would like something similar for the playlists on the left margin. I have "Music", "Audiobooks" and "Movies" as separate media folders configured, and if I choose "Audiobooks", I'd like to only see playlists that have audiobooks. And if I choose "Music", I only want to see my music playlists.
