Would it be possible to add the option of clicking on an object which would pull out a new canvas from under the object to present additional details without zooming / moving and then users could return to the base layer by closing the top canvas. By allowing to use zooming on the second canvas as well, you could multiply the ability of Prezi to present increasingly complex concepts or data and further decrease the “motion-sickness” factor. Please consider. It would be probably relatively easy to program as well.
Nagyszeru munka, hajra magyarok!
