I have been using Subsonic for a few years now and love it. Somehow i just figured out about the Tag Editing Page. I was very excited until i realized i could not edit file names. Tag editing looks nice for subsonic, but I also run AirVideo Server and Emit Sever for non-web clients. Since they don't reference tags, the files would not be renamed there.
Currently i have to remote into my Subsonic server and manually rename files. I also manually move them from one section to another. For example, I buy a TV show, and it immediately goes into my "recent" folder where all new additions go. Then, once i watch it, I move it to Recent-TV (or recent-movies, etc) until the whole season is complete. Then I move the whole season to a larger hard drive (TV1,TV2, Movies, Music, etc) for final storage with the rest of that shows seasons.
If i could edit the file name and move files between media folders all from within the subsonic web interface, that would be very helpful and time saving.
