Greasy Fork is available in English.
It will make some of your youtube videos louder, the reason why this is possible is because sometimes you can slide to 100% music output, but youtube validates it in it's javascript to a lower music output then 100%, in this skript I make a new slider which makes your youtube videos always the maximux output when you make your videos on 100%
