I like the collection tag filter for organizing files by different criteria. How hard would it be to arrange the same sort of three-way sort for the playlists? Useful sorts (to me) would be artist/album/track.

Another thing that would help is a way to get a bit more information from the cover manager. Sometimes I can't tell which file it is talking about from the short strings that display under each icon. A way to pop up the "Edit Metadata" window would help. Sometimes there is a file with a typo in one of the fields and it is awkward to find it.

thanks,
