I had an issue where my host was working on ffmpeg for most of a day. I had about 50 videos that were uploaded during that time. None of them converted. They are on the server, but not posted on the site. They are basically useless and need to be deleted. But to do that, I have to go into each one, one at a time. It would be much easier if there were check boxes on the All Videos page (and All Users for that matter) that allows me to select multiple items to delete at once.
