This is a basic structural change, but one you really need to implement.
There is no reason for AutoDJ FILES to exist. All you need to do is add the features of AutoDJ FILES (upload, delete, etc.) to AutoDJ MEDIA. This would make Centova a much easier system to use and less of an atavistic throwback to 1998. Searches and file movement / addition / deletion etc. could and should be done from one window.
