Gray Out Area fix -> It was Grayed out to much, not Only the Control in the Design Panel.
Support for DesignTimeProperties wich are not defined in Assemblys
like x:DesignHeight, x:IsHidden, etc...
Support to hide Controls from the OutlineView.
XamlDesignItem now ICloneable is now implemented!
So for Example you can clone it in the Outline View
Copy & Paste of Items -> Keep the old Position, don't move all Elements to the upper corner.
This works, because before the Action was AddItem, and then the DefaultPlacementBehavior tries to set the position!
This should not be done by paste from Clipboard
Set ClipToBounds inside WindowClone so only the Controls are Visible Area of the Window are drawn!
 Canvas Position Handle
-> When Positioning in a Canvas, show a Handle like the one Showed when Positioning in a Grid
Enum Button -> Highlight Selected Value
Extend Zoom Control so that it can Display Additional Controls.
Used later for Enabling Grid/Snapline Placement support
- Raster Placement support!
- Aviability to Enable/Disable Raster and Snapline Placement from the Zoom Control (like in VS2012)
- Fix in Snapline Placement that you can also Position to 0!
