Add mini timer on slides.
Often you have very limited time on performance, and every person want to know how much time it have to make the presentation in time. I think it would be very useful and cool feature to know hou much time you have directly on slides. Maybe mini timer at the bottom corner of slides. And very cool if i can to configure it. For example I have an hour on performance and i have presentation with 20 slides. So i know that i have approx. 3 minutes on each slide. So i configure this built-in timer on 3 minutes and i can see elapsed time on each slide to talk about this slide during my performance.
Sorry for poor English, i hope my idea will be clear
