There is, well was, a browser called Rockmelt, it had a direct connection to Facebook. It was slightly similar to chrome but it was funded by Facebook. Well Rockmelt had the “Friend’s Request”, “Messages”, and the "Notifications buttons up top, online friends on a sidebar, and had other sidebar with other “news” icons on the other side where you could put Tumblr, Facebook, CNN, etc. If you clicked on it it would bring up a small window that had the news on it. It looked like this when it was disconnected. http://cdn2.pcadvisor.co.uk/cmsdata/reviews/3340641/Rockmelt.JPG Just an idea.
Instead of creating another chrome based browser (which they already have), they could add a sidebar thing that does the same and allows users to disable or set options for it.
