I'm one feature away from making this my main twitter client on my phone: when I save a web app made to run by itself as an alternative or replacement for a native app to my home page, opening it should by default hide the trappings of the web browser. The constant pop-in/pop-out of the header and footer makes tapping on things just obnoxious enough to make me not want to use it. I know some web apps have removed them, I just don't know why it isn't more common. Also, it has that little bar at the top to open the site with the app. I feel like that should've been the first thing they got rid of.
