I'd like a way to edit all a tune or playlist's properties in JEmplode, not just the ones that appear in the database. Emptool allows setting of arbitrary properties.

For instance, it would help me organise my "singles" playlists if I could add a "release date" property to them all, and then use that field to sort them. Emptool lets me add the property, but it doesn't sort playlists. I could use the "comments" property for this but (a) I tend to use it to annotate marked tracks with the reason for marking, and (b) that's using space in the DB for information that's not useful player-side.

It would also enable the removal of obsolete properties from previous versions of emptool.
