I don't suppose the current version supports the idea of detaching tiles as you drag the tile outside of the tilescontrol, but could you suggest a way I might be able to extend your classes and achieve this behavior?  I'd like to have tiles swap as you drag items within the frame of the application (default behavior), but also tear off into child windows as I drop the tile outside of the window frame.  Many docking frameworks support this behavior and it's a logical addition to the tiling framework.  I'll keep playing around in the meantime but if anyone has any thoughts, let's collaborate.  Thanks.
