I believe in the previous version of the Lifesize App we had the capability to pop out the presentation into a separate window. This would allow us to throw up the presentaiton on one monitor, and view the video on another monitor.
And, sometimes, it is very difficult to see the presentation, and we have to ask the presenter to zoom in. We should have independent control of the zoom of the presentation. This should be a feature in the popped out presentation window.
