I was trying to figure out how to change the background window colour from white to not white. was pointed to grid.lua line 276 by a helpful person on discord. was told that since that's a system file, I would have to change my startup file to see the changes when I reboot.

well that's not the case. I am able to make changes to various system lua files and the changes survive rebooting :S

it even says at the bottom of the image that changes wont be written to disk...

I just got picotron, tried all the demos. just wondering how to close birds.p64? I know I can just reboot but is there a way to force close it?
