This add-on honestly seemed really great when I started using it, I mean, I really appreciate the customization it gives! I'm only giving it a one-star review because it just slows down Youtube a TON.. I'd gladly use it again if it was optimized though.

I definitely wouldn't recommend this if you intend to not make your Youtube slow.. also if the developers are seeing this, please optimize this add-on, it's the best one I've found for these things, but it just sucks when it comes to speed (also some settings just don't work for me..? not sure why, as I don't have any other add-on).
