I like the playlist mixer.
But sometimes I want to include ALL the tracks that match a specific selection criteria. (For instance, all songs with a rating of 5)
Currently the only way to do this is to count how many songs match that selection criteria, and then telling the playlist mixer to select that many tracks with the criteria.
This works, but I would prefer to be able to add % to any track count box to treat that value as a percentage rather than a strict number of tracks.
