Next and Back buttons gone from Review Quiz when controls and menus hidden in Modern Player

I came here looking for an answer to this same question, because I've disabled the player controls in order to give as much real estate to the content, itself -- I've recorded a simulation of a screen where the UI labels are sometimes very small.

But hey, just thought of something. Would it work to put hidden Next buttons on the quiz questions themselves but trigger them to become visible only if someone has already visited the question?
