Cool. But dammit why aren't tabs more modifiable. I want to rename them. I want to assign an icon. I am okay if a tab takes up two vertical lines to make it entirely readable. There was an element of something really useful in MS 'Metro' UI -- just the fact that there could be variations in size of target/icon/links. I currently 'pin' my mail and notes tab. These exist as specific functional tabs -- let me style them a bit differently or something.
