Kai It would be neat if you displayed the number of Open tabs in the Tab Icon. (Inside the square probably)
TheOtherKai In vertical tabs, i'm thinking it's like the collapsed tree tab thing, except on the open tabs text?
Kai Those two squares. You could either write it smack in the middle like FF does it: Or you could just do some kind of notification badge kind of thing
Vlad Kai Perhaps we can make it an option "Show tab count in the icon" and enabling it will switch to the view in your second example
