Nice, but the back button still spends the scroll, right? That’s how it works right now as well unless something changed recently, you use your scroll or it goes poof.
Then again I am wondering why there needs to be a back button (or as of now, cancel button) if you are just being asked if you are sure, since you are going to lose the scroll anyway. Like, in what situation would that be something one would want to do?
