How do I use a DelegateGroupDescriptor to group by a certain key (a GUID in my case) but show a user friendly value in the group header on the screen (i.e. Recent Content)?
Also, the scrolling seems to get messed up when you have a several hundred items and select an item at the bottom of the screen, the scroll bars jump around and the item you selected goes out of view.
