• Ability to drag tracks from a Playlist to the Queue pane.
• Ability to drag tracks from a Playlist to the Queue tab (if not currently showing the full Queue pane - e.g. if viewing the Collection pane)
• Ability to drag items up/down in the Queue pane (vs. using the up/down arrows at top). A direct interaction is more intuitive and simple.

Related: not sure if this is the intended design.
If you have tracks in the Queue, stop playing and then add another track to the queue, the track you just added starts auto-playing. It seems odd that it would jump past already queued songs and be the first thing to play...

Thanks!
