This feature is a great addittion, but it dont work for me as is.

All my shared files are nicely organised in artist/album directories. If I want to see the files most hit or uploaded I have to go through each and every directory.

I think that in the library view the name column should also include a relative path. E.g. if I have :

../Music/Artist 1/Album 1
../Music/Artist 1/Album 2
../Music/Artist 2/Album 3

Clicking Music in the dir tree shows all files in all these folders... Selecting Artist one shows album 1 and 2 ... etc
