Add a pause button between the green flag and the red stop button. What it basically does is stop the project, and if you click it again, the project doesn't restart but starts from the point you stopped it. This could be useful when you are actually playing a game, rather a hard game, and you cleared most of it, but you had a temporary call… You had to go somewhere, leave the game temporarily. So you can pause it, and restart it from the point you paused it. I think it'd be useful.
