Toggle queue status on Shift+Click instead of just adding
Some time ago, it used to be possible to add and remove tracks from the queue using a middle click. #2003 (closed) partially restored that functionality by adding tracks to the queue on Shift+Click. However, it would be very useful if tracks that are already in the queue could also be removed by a second Shift+Click. Currently, this can only be done through the right-click menu. Thanks!
