It would be really useful to be able to view which tracks are in a filter group within playit manager. Currently you can view a count of how many Rock tracks there are for instance but can't see a list of what tracks they are. This would be useful for managing the genres of songs. You would be able to see a list of Rock songs and easily edit ones you didn't think were Rock for instance. Ideally the ability to filter by genre would be available everywhere you select a track in playit manager. For instance if you had a rock show and you decided you wanted to change one of the tracks in playit manager currently you have to know the name of a Rock song you would like to change it to. It would be nice to be able to change the list to only display rock songs so you could browse for a suitable one.
