Comment 42 for bug 671632

So I'm testing to what I've done so far. It works with my builds.

I downloaded windows VM to test other DJ softwares. So far I managed check out Serato intro which uses crates in different way which, I think, is much better and I'll probably change my implemetation to copy it. This means no folders, just crates containing crates a showing content of all subcrates. This allow also "tagging" usage we were discussing earlier easier.

Also I think we'll need to implement drag'n'drop to make tree structures comfortable with.

Glad for any feedback.
