Duplicate/Copy the existing screen(Whole Screen)
It will be very useful in real project. We can try different approaches base on one rough design.
It is very simple: MS don't need to parse the internal elements, just give us the whole screen file copy!

Thanks for your idea! You should check out this extension that clones screens from Xpert360: http://visualstudiogallery.msdn.microsoft.com/c3774d50-a695-4a89-a8d0-6f0b55711ad9
That's great idea
