Maybe I'm just overlooking the obvious, probably I am. When I open the images editor or gallery, I would expect that I could delete one of the uploaded images, and/or folders, but I don't see a delete button anywhere. Do I need to do something to make the button show up?

Nevermind, I just found the little 'scissors' image right above all the check boxes in the file list. I knew I was overlooking the obvious. Actually I was expecting a 'X' for delete instead of scissors.
