Quite awhile back I posted a change request on the feedback portal to get support for the RadWizard in the Document Outline window of Visual Studio. Unfortunately, I've been informed that even after nearly two years it's still not on their plans due to low demand.
The Document Outline is an amazing feature with Visual Studio that allows you to quickly see the hierarchy of your WPF XAML. This is invaluable when you have complex layout -- which you probably have unless you're dealing with trivial solutions. Most controls enumerate all their children. The RadWizard swallows it up and displays nothing (image added to illustrate the difference).
I'd appreciate everyone reading this to take a look at the Document Outline feature if you're not already familiar with it, and once you do I hope you'll see why the RadWizard needs the support and then please go and upvote my feedback.
