Through years I have made lots of playlists of different "personalities" and combinations. (I am a radio DJ and some friends parties) At the end of each event I save my playlist)
Sometimes I need to combine some of them with parts of other lists.
It would be extremely useful if I could search for the track on the root of Playlists tree and all lists containing this track to be hilighted. So I could enter each one and check the combination and the "personality" of each one list.
I cannot confirm this. The search is disabled for AutoDj though, which is intended to not play hidden tracks, which could be surprising.
