First, being able to skip the spinning animation (since the item is decided when the tokens are used). Second, for those who save up their spins, being able to spin multiple times so we can get through several hundred spins faster. 5 and/or 10 is a good number. Support?
I skip the spinning animation by pressing the home button and then switching back to the still-open PIMD tab.
I did equivalent when burning through almost 250 spins. It caused a few graphical issues. My button was the switch programs button (android device). Besides, for multiple spins, it would need to skip the animation anyway.
