Great!
I can see sorting of collection (very well done, btw).
I was thinking of moving single songs in the playlist or queue.
right now yo can long press on a song and "remove". Would be great to have an option to move a song up/down within that list.

Another great addition would be an option to "play next" a song from collection view, instead of adding it to the end of the playlist.

Already now, this player has the best playlist handling I've seen on Sailfish so far!
