I would like it if the question would come up and then there was another step where you could click to reveal who would be playing that question. This way, I could have the whole class preparing to answer the question and then reveal who would have to answer it aloud. I had an administrator come and observe a boss battle and they didn't like that one kiddo's name was up there and everyone else knew they were off the hook for that question. This would also be great for teams. I would have all teams prepared to give their answers, but no one would know who would be called upon beforehand.
I would also like there to be a sharing boss battle like for quests. I would like it to be more like Kahoot, however, where you can see all of the questions before committing to download it.
