Hangouts add-on

[The Rock]

Hi guys,

I have a friend who claims he knows (among other things) when someone opens his chat window in Google Hangouts. He has some sort of app or hangouts addon. Has anyone heard of this?

Go into Hangouts, swipe to the left to see your contacts....see the little chat bubbles next to the names? If its green it means they're online. That's probably what he means.
