I don’t know when this feature was added to Google Chrome, but now if you right click on a tab you can pin it: the title of the page and the close button will disappear leaving only the favicon.
In this way you can keep always open your most visited sites, like Twitter, Facebook or Gmail.

Very interesting, despite the fact I Today updated chrome and I cannot find the fature
I always run the development version of Chrome so maybe this function is not yet enabled on stable or beta versions.
Oh, that’s why, maybe.. :-)
Nice blog, BTW :-)
