A message to Shantanu:
Shantanu nothing but my first button works. I genuinely have absolutely no idea how to make the other two buttons. The code for the second button is probably doesn't make sense but I tried. It's also in a comment because there's some syntax error I can't find that prevents my one and only working button to work. I tried to fill in some code for the third button because I kind of knew what I was doing but I didn't know how to actually do it.

I don't know when and why this photo was taken but what I do know is that this was posted on their twitter.
