zooming in on the ipad

Edit Subject

Hi!
One of the great features of PREZI is the way the canvas holds all the pics and text and iformation. I am frequently using the iPad PREZI app now to give scientific talks (biology). In the discussion followowing these talks people will alsways jump from topic to topic (picture to graph to whatever) and you need to go back to these points in your presentation. Doing this in PP or Keynote is always a pain, as you either have to go back and forth through all the slides or drop out of fullscreen mode, pick the slide and go back full screen. In PREZI you can zoom in and out just like that, which is cool. I think however the zooming in process could be improved even more. What would be really cool, if it was possible to go to a certain frame in your path from the birds eye view of the canvas by tapping an holding the frame for a short time. So I go to birds eye after my talk, somebody asks something, I know where the point he/she relates to is on my canvas, I touch and hold with my finger an zoom in by that. Actually it would even be better if you have two differen speeds of zooming in, like press and hold for, say 2 seconds, and it zooms in at normal speed and if you hold longer it does a hawks dive at 300km/h at the selected frame. This would allow for going to a place on the canvas slowly when you are not exactly certain of the right frame (or there are several next to each other) and going somewhere really fast when you know exactly where you want to be.
Best
