Who needs User Experience Managers? Just kiddin.

Should relace the More Button with a range of easily understood Icons.
Full Screen, Autoplay
Autoplay Controls need to be more specific. Need a choice of the number of times the Prezi should be repeated. e.g. 1-5 times or Forever.
Need a choice of 4-20 seconds.
Need to allow for length of embedded Youtube videos. At the moment the video cuts off after 4 seconds and continues with the Prezi in a loop which is not easy to stop till the video is completed.
When playing the Youtube Video the “X” button to clear the Google ads does not work so cant clear the adds.

Thanks for the suggestions. We’ll take a note of that for our feature request.
