title: Can I customize AvalonDock context menu?
body: <p>I am using AvalonDock in a project to take advantage of the tool windows.</p>
  
  <p>I don't have any need for Tabbed Documents and would like to disable the "Dock as Tabbed Document" context menu item when I right click on a tool window title bar. Is this possible?</p>
  
  <p>Thanks</p>
