Great overall, but lacks an important feature (have to use another extra extension just because of this): quality selection for videos. Options might be like highest, 4k, 1440p, 1080p, 720p etc. Would be great to have this feature in next version and it should be very easy to implement I think.

Edit: And maybe hiding "only member videos" in a channel's video page feature would be great. Not only as an option but like as a button in somewhere to switch between it quickly.
