Since v6 (or was it already in v5 ... I don't remember), the playlist is hidden and displays when mouse hover the control panel.
Hiding the playlist to gain space and have a bigger view when displayed is great but what is terribly annoying (at least, to me), is the fact it is poping on mouse hover.
This is very unpleasant when dealing with huge lists and it works quite badly with touch screens.
I know there are keyboard shortcuts but navigation with keyboard is far from perfect especially with big lists.
I would definitely prefer havin the "currently playing" list in a new section or at least, having it poping up or out on click somewhere instead of mouse hover.
Best regards.
