I decided to use the RecentDocumentMenu and Manager. Since it needed to look quite different from the default one I changed the template as needed. I have only one more thing to do. I like the pinning functionality but I would like to capture that event in my ViewModel. From the xaml I see that it the pin button executes
<Setter Property="Command" Value="{x:Static Input:RibbonCommands.TogglePin}" />.
I cannot change that, but I would like to register for a document pinned event so that I can do some processing. I have no clue on how to do that. Any suggestion?
