Thanks for adding this feature! Although I'm sure it works well just from the code I can see, I need to ensure that when the option is toggled off, anything added by the feature is removed. I can add this myself if you want or you can do it, but either way once that is done I'll merge this.

I try to do this for most features just in case something goes wrong so that the user can quickly disable it, even though this looks solid. I can't see anything going wrong here, but this is especially important for quizzes because I wouldn't something happening and jeopardizing someones quiz grade if there's a glitch.
