Similar to the ability to move additional files, the ability to delete these files would be very useful. I use embedded artwork and get rid of everything else before tagging (I usually just search for all the extensions I know of and delete them all at once) but it's getting to be a little troublesome because I forget some of them and then the delete empty directories doesn't work. Not the biggest issue as I usually just delete the folder later anyway. Picture attached in case I'm too drunk and don't make sense.
