Keyboard bindings and full screen operation
I love using the keyboard and much of my time is spent online checking forums and reading stack overflow posts and emails. Please make sure that you have customizable keyboard bindings which allow users to control all aspects of the browser. For ex - I hate chrome because in the preferred full screen mode, it does not allow me to access address bar. Ideally I would like to use my browser in full screen mode and never come out of it.
