He he the easiest solution is to put the window in full screen and thats it😁
I dont know if i am watching something than i focus on that. Prepaire the food or snack and thats it. Nobody cant disturb me because i became angry😁
But yes this can be a usefull extension for those who are close to the pc and they are doing something else also beside of the watching.
Different people different needs.
Still it is a good hunt just i shared my own opinion😊
