The extention I think is cool, is an extention to help code and make a on screen joystick to make games mobile. If there is some blocks to help with that coding then it would make it easier to code and help out people using mobile. Like me. I use mobile. It could also help out with understanding the coordinates for people having trouble making mobile games. It would help with mobile devices since there is alot more lately. Most games are computer and most people I know on Scratch, besides a few people, use mobile. So who agrees there should be an extention for this?
