My favorite browser for Windows Phone, Surfy, got a nice update yesterday. The application bar at the bottom of the browser now minimizes itself when scrolling a web page. Not that big an update, but a most welcomed one on small screen devices and bigger ones too as you get more viewing area. This feature is activated by default after installing the update. If, for some reason, you would like to disable it, you can toggle it off in the browsers settings.
Surfy is available as a free and paid app in the store. The only difference between the two is the number tabs which is limited to three in the free version.
