- I sync to mobile devices using playlists exclusively, so it would be useful to be able to scan down the entire music library to spot which tracks are not currently on any playlist
- When editing duplicate content, it would be of value when an item is selected to see which, if any, of the duplicates are assigned to a playlist(s); this would influence the decision regarding which one(s) to delete and/or whether to edit the playlist(s) 'membership' of the one that is 'kept'
I appreciate that, with the Properties dialogue open, the tracks can be stepped through with the Alt-Right key combo to display the playlists of each successive track, but this is still not as useful as seeing playlist membership in a column or columns of the main view, for all the tracks in that view.
