This browser is getting really really good! But I have a possible improvement that I think would make it even better:

* It would be nice to have a pulley menu at the bottom with an option to close the current tab. Think it could give a quite natural workflow - When a page been scrolled all the way to the bottom, and user probably is done with it, just scroll/pull down a little bit more to open a menu and close the tab (and maybe some other useful options).
