coding is SUCH a pain!! i'm in my app dev 3 class n AUUGHHH it's too much for my little pea brain

thankfully, i'm not the worst at it, but i'm also not the best. HOW IN THE WORLD do i make an undo and redo button in a paint program......... i'm just gonna turn it in the way it is. at least i got almost all of my ideas down...
