hi there! :) Please try again. This project is a rare sisyphos-mission going on since 11 years and for 580 000 users. Please report any bug you might find in detail in our github. We don't set any non-standard youtube hotkeys but only inform you alone the way what are the standards. (This is supposed to be efficient/minimal design, like Apple). The volume boost can be set permanent or a quick button be added easily by a beginner as we prepared well. However i cant do everything alone and might prefer unique work. (You can use any other volume boost extension.) Thanks
