Facebook Chrome Web Store app is out and taking names... well, not really. As of right now version 1 only directs you to a link with "ref=cws" so that they can track who comes their way from the app. It seems it should do something more considering that it could have deep integration into every webpage. Their Help Center does not even find a mention of the Chrome Web Store.
I will be waiting for the next version. At least for now I have a sweet Facebook icon on my new tab screen. Party.
