This feature makes presenting from a Chromebook look professional. Without it I will have to drag it over, then put it in full screen mode. Part of the purpose of my upcoming presentation is to demonstrate that a Chromebook can be used as a primary productivity tool. My audience will NOT buy in if I have to drag the slides over.
