ModernTab Tree View in Left Nav

Jan 22, 2015 at 2:12 PM
Is it possible to get a TreeView instead of a List for the ModernTab left nav?

Perhaps something like this:
<mui:ModernTab SelectedSource="/Foo.xaml" Layout="Tree"> 
Since MUI was extracted from XML Spy, and XML Spy uses a TreeView in its left nav, I would imagine this is possible.
