Have a sound play whenever there's a response.
I've made a live "I don't understand poll" for students who don't understand what I just said in lecture. If I see responses I would back-up and repeat or expand on the lecture point. Sometimes I don't know if there are responses without looking at it, so it would be nice if it could play a specific sound to let me know.
Thanks for your feedback and interest in Poll Everywhere!
That’s an interesting idea! We’ll put it under review and talk about it. We’ll also let other users vote on your idea.
