Can you please change a little bit twitter sharing thing. you can use :
http://twitter.com/share?url=http://someusrl&text=here is text-%20&via=qmlreddit

As well to add minimize button to all windows, as the fullscreen is default, and you even can't change it if you browsing picture or anyother link (i like to do read twitter for example while it is still loading).

And when you change topics, there are some buttons unaviliable under cancel button
