Possible to switch to a full-screen webcam view?

When my campaign switches to a non-combat scene or we simply want to role play, I never know what view to show my players. In these cases, where they don’t need to focus on the layout of any particular room or area, is there a way to just switch the players to a full screen page of all our webcam videos? Or even just me as the DM so they can see my face more clearly? The lack of face-to-face interaction is my primary hesitancy to use Roll20, and this would help immensely. 

While you can't control how individual users display their interface, you can switch to an all-black page, focusing attention to the video feeds. You can also set up a Theater of the Mind page. I give an example here which uses the API, but there's nothing there that couldn't be done without automation. I used to set up individual pages for this before I jumped to Pro.
