Visual Studio 2013 Web Editor Features - HTML Editor

Scott Hansleman shows how the Page Inspector feature in Visual Studio 2013 allows you to work interactively with the rendered page markup, fully integrated with the source code that rendered it.
I friggin love the Page Inspector. So helpful for finding where something came from.
Too bad this only works for web pages (for which there were already tools).
Is there anything like this for XAML / WPF?
Thanks! Very helpful and, almost as important, quick.
Where can I find this app to test it?
