Media Library: "folder" column and filesystem sync

[janez1977]

I am trying to organize my (mp3) music collection and am faced with following shortcomings(?) of Media Library:

• No "folder" column: I'd like to have a column with info on filesystem location of the file, since lots of my music is already organized this way.
• Poor synchronization with the filesystem I: I'd like Media Library to be able to reread a folder and remove any file that not exists any more.
• Poor synchronization with the filesystem II: I'd be great if deletion of item in Media Library would also delete corresponding file on filesystem. We would then have two commands, something like Remove from Library and Delete from Computer.
