If you are a heavy user of Hangouts and use Chrome or Chrome OS, there is a new extension and app for you to check out. Last week Google announced that a new, Android-like Chrome extension for Hangouts would be coming out with the aim to improve performance and the overall look and feel of the UI. Achievement unlocked as both the extension and the app look far better than the old style and both perform exceptionally well.
The new extension can be found in the Chrome Web Store which allows you to run Hangouts while you are using your Chrome browser regardless of platform. This is what the majority of users will want, especially Chrome OS users, as the browser tends to stay open all the time.
