In Amarok1 I used to load some files into the playlist the organize them into my collection.
Unfortunately in Amarok2 there is no such option, I can only organize files which are already in the collection.
Could that be implemented?

+1 request. It is very important to edit and organize my collection. When i get new tracks,  i edit them on the playlist and move with organize collection menu. But i cant use this feature in amarok2. Please can you suppose a solution. Thanks.

Have you looked at the "files" browser? It's one of the tabs on the left, below the collection tab etc.

Thanks! There it is.
