Newbie: Fullscreen Webcam

Hi All, Firstly, let me say that I am a new to using roll20 and I am done so straight away as a GM. From what I can see so far I am very impressed and the tools available are incredibly easy to use and get my sessions setup. Due to working away I am planning on sometime GMing my sessions remotely and Roll20 has come along at just the right time to allow me to do so.  I have what is probably a simple question to answer: Is there anyway of making a particular Webcam from the player bar into a full screen video? I know that there are plenty of fullscreen tools to do this with, but I wondered if roll20 had this capability - it'd make switching from narrative to encounters a bit easier if I could figure this (if it's even possible!) Thanks for your time, Rich

most of us use roll20 for the mechanics and skype /hangouts./teamspeak/ discord services for video and voice as needed. 

A little bump here, but I am also curious if this is a possibility. I have been trying to encourage more theater of the mind, as well as giving my players an "at the table" feeling. So I run my webcam with me sitting at a table behind a DM screen rolling dice, and I would love if I could make the entire roll20 my webcam so between battles they are focusing on me instead of my little icon at the boom. I know that Skype, Discord, and the such have full screen capabilities, but my players would never use it. They already complain on how cluttered Roll20 is, and I believe that outside of using a 2nd monitor my players just wouldn't switch back and forth between the two (most of them use laptops).
