I am extremely impressed with this addon. It is very well integrated to the point that I often forget this is a third party extension and that YT hasn't altered it's UI. I would give this a 5 star but I am too much of a perfectionist and am waiting for very minor improvements to be made before I jump to the full 5. Till then it is a 4.8/5.

Dear Dev, this is an amazing ext and I thank you for it.
