Right now if I add one of Pandora's custom playlists they make for me (which are incredible and a BIG reason I moved over from Spotify) it shows alongside any custom playlists that I've made for myself.
I would love to view those separately. One drop-down for "My Playlists" and another for "Pandora Playlists".
Sometimes I want to check out the selection of new stuff they put together for me, other times I want to put on something specific. Keeping these separate would make the interface SO much cleaner, especially since I am going to be making a ton of custom playlists for myself.
