Used to be perfect, but now, it will only remove the initially loaded videos from any particular playlist, which is 100. If you have say 2000 videos in there, you now have to do it 20 times with refreshes in between, etc. The extension will act like it's removing videos if you load more than the initial 100 (either manually or using the plugin) but the videos will not be deleted. It's not user friendly to just let users discover disfunction on their own, as it wastes time and is very frustrating. It does still seem to copy videos to a new playlist when loading the whole playlist.
