Consider adding an "Are you sure you want to quit?" prompt before quitting apps. I've accidentally exited games multiple times now and lost progress because the system immediately quits the app without asking if you had selected quit by accident.
I know that a simple solution would be to not select "quit" when returning to my games, but sometimes I'm not paying full attention and select it by accident. Before I realize what I've done, it's already too late! Please consider adding this option for those of us with short attention spans!
