As it stands you could open Other CB Clients in another window (or tab), giving the option to select the CB interface desired while retaining an open window (or tab) on the Monastery, allowing browsing as normal to continue. I don't see an advantage to losing focus of everything else purely to present a full screen CB interface, however I am sure, if desired, people could position their free nodlet above the Chatterbox node, and link to a full page chat window.

Thanks
