Since the upgrade to v3 (which is excellent, great work!), it doesn't seem like you can remove multiple tracks from the queue (other than clearing the whole queue of course).
As far as I can tell, the only way to remove a track from the queue is to swipe each one individually. However this is tough when you want to remove a decent number within the queue as you have to swipe fully and the animation can take some time. I'd love an option to the "N tracks selected" three dot menu to remove the selected tracks!
