I've tried to find answers in the forum an Wiki, but have not succeeded. Here are my questions, concerning both Duet/Controller and Squeezeplay.

-I often use Random Mix to re-discover my music and occasionally I want to add specific tracks to a playlist (new or existing). Any way to do that?
-When I play a Playlist, I sometimes want to delete a track. If I use the Controller to "Remove (track) from playlist", the track is skipped for now, but not deleted from the saved playlist.?
