Yes, this is coming in Windows 8. http://blogs.msdn.com/b/b8/archive/2012/05/21/enhancing-wind...
>My biggest complain pre-Windows 7 was that you could not reorder items. I thought they fixed it, but they actually made it a lot more annoying with W7. I think Windows assumes that each window of an application is related to the other windows (never the case with my workflow) and so you cannot separate them by dragging. Say I have 5 Firefox windows with a few tabs each, where each window's tabs represent a collection of related topics. Now say I have some Word and Excel documents also open that relate to the browser windows.
