Implement "Item to Item Snapping" during item resize operation.

Users need a way to control the way SettingsPane is positioned.

Extend the layout mechanism to allow control over the layouted elements in order to exclude all disconnected shapes from the layout and reorder connections by their target connectors.

Add ContainerShape ContentTemplate and ContentTemplateSelector properties in RadDiagram

Currently there is no straightforward way to notify that a point is added/removed from the ConnectionPoints collection of the RadDiagramConnection.

There should be annotations (comments) system built into the framework:
€¢something like Word where one can add to a word a note
€¢something like Excel with its comments bag
€¢something like Workflow Foundation where every shape has a popup bag

PathTool: Possibility to edit the shape path via edit points like the Pen Tool in Blend.

Import from DWG files needed.

When zooming out on more than 500-600 shapes and then panning, if telerik:DiagramSurface.IsVirtualizing="True", the performance is slower. 

When virtualization is off, the performance is a little better.

Extend RadDiagram to support natively Venn Diagrams.
