Unfortunately, the hard truth is that windowed applications in OS X aren't a well-behaved enough bunch for anything like this to work anytime soon. In 2010, I collaborated on a project to bring some of the features of my 2009 10/GUI concept to MacOS. We got it to a point where the likes of Safari, Finder, and TextEdit worked great and could have made a nice demo video, but the moment you threw in something like Photoshop, which took its own approach to windowing (or iTunes, for that matter; it certainly wasn't just Adobe), everything broke. We never got beyond a proof-of-concept. As I've said before, a better approach to windowing on OS X will eventually come from the full-screen API in future versions of the operating system: http://interuserface.net/2011/07/10-7gui/ http://interuserface.net/2011/07/10-7gui/
