Can someone that codes userscrips make something?

I asked for berserk mode in regular games. But since that is not happening can someone code the button for stylistic purposes so that I can have fun in non tournament games with it? Ill pay you 10 bucks to do it for google chrome. If a lichess dev does it I will donate 15 dollars to lichess.

This would mess with ratings, a bit. And if you want a lower time, it is easier to go to a game with a lower time control, anyway. I don't see the need of having a "Berserk" option in non-tourney games.
