I don't really see the point tbh.
I never browse for other stuff to watch while still watching a video. Even on mobile, where this is the default behaviour, I always dismiss the mini player instantly.
I really didn't like playing online against other people always felt like I was being matched against children... Sorry it's your 7th birthday but I guess I'm supposed to mow you down anyway...
I have reflexes a cat would be jealous of and a near psychic ability to read people, makes online play feel incredibly unfair. Ironically I have been booted from online servers for being a bot.... Or aim assist lol
