I have a similar line of thinking. I’m a musician, so if I was filthy rich I might want to donate money to a school’s music department. If the school is one fiscal entity, I would have to put that as a stipulation to ensure they gave the money to that department, not divert it to something overfunded or just padding the board’s pocket as bonuses for “a job well done”
They have left-hand hardware that has a thumb analog stick and a bunch of mapable keys. Problem is getting games to use “controller” functions like analog sticks and mouse functions at the same time. I haven’t tried it myself, but apparently most games don’t have a way to recognize and use that as a keyboard function
