Are you looking for an extension that will allow you to see all the active hangouts in your stream? With this extension, not only you get to see public and limited hangouts, you get to capture their moments really quickly. It will take a screenshot of the hangout (including the plugin) and allows you to save it for later or publish it to Picaso under a folder called "My Hangouts".
People may ask what are the main differences from the other extensions out there:
Basically, this extension just presents another view to see hangouts, that is all!
