Also be aware that this extension is built on experimental Chrome APIs, which means that you'll need Chrome Canary to use it. Additionally we can't upload it to the Chrome Web Store until the experimental APIs are available in the Chrome stable. Yes, we are living on the bleeding edge of Chrome extension development, but that's only because we want to provide you with features that can't be implemented in current stable Chrome version. It's just a matter of time until the needed APIs are stable, and installing the extension will be much easier.
Check out how to get the extension, then watch the tutorial below to get started.
