Not sure if I've got the right terminology.
Most apps in Win8 have a "siderbar" mode where you can drag them to the side and they take up a portion of the screen and alters the interface to suit. Is there a way to get this version of the app into a windowed mode? This would be useful for things like Twitter or IM apps rather than having them in a large window or trying to squeeze the large interface into a smaller window.
Does this feature currently exist?
