Other Extras in Hangouts
Besides mobile and broadcasting Hangouts, there are some new extras within Hangouts. The new screen sharing feature lets you show off your vacation photos, your high score, your lesson plan or whatever else is on your screen. Sketchpad is for doodling, scribbling and drawing. And Google Docs work now within Hangouts, too. You also can access Named Hangouts, which lets you join or create public hangouts.
