Google now makes it "just a single click" to set up "Video chat, voice chat, and group chat" features within Gmail. One of the more subtle benefits to surfacing these chat options is that it's easier for people to get started who don't yet have the voice and video chat plugin. If your chat buddy doesn't have plugin, clicking on this icon in chat window will invite them to install it. As soon as they're done, you can carry on with a face-to-face video chat. Since we launched a similar feature on iGoogle and orkut a little while ago, we've seen a dramatic uptick in people using video chat. Finally, you'll find oldie but goodie features such as "Go off the record," "Block", and "Send SMS" in a more aptly named "Actions" menu of each chat window," noted Google.
