Even though there are workarounds for everything, from my point of view the diagram control will be much enhanced if there are a few events added to it. Just as there are events for a shape having been clicked and double-clicked, in my opinion it will very much help if there would also be events exposed for a shape begin edit, end edit, preview delete (so as to handle a delete event), even generically a PropertyChanged event for any shape in the diagram. And the same for connections would, I imagine, be useful in other scenarios (even if not mine, currently).

These are all events I’ve had to handle some other way (sometimes in quite convoluted ways :P), I’m sure there are others which would make life easier for programmers in other scenarios.

If you add a background brush to the image export and the export DPI is different than 96d the brush won't be exported correctly.

RadDiagramContainer is resized unexpectedly if you try to align it and its children to the top, bottom, left or right

Fixed in LIB version: 2014.2.0914

When using animations on refreshing the layout of a RadDiagram (LayoutSettings.AnimateTransitions = true, then calling Diagram.Layout or Diagram.LayoutAsync), if you have a RadDiagramThumbnail "synchronized" with the RadDiagram... well, the synchronization does not happen automatically (just this I believe is a miss on the part of the Diagramming Framework) and, if you force it with a call to RefreshThumbnail(), since both the Layout and the RefreshThumbnail processes run on the UI thread they seem to collide and the result is the thumbnail isn't correctly refreshed either.

Obviously, best would be for those theoretically-synchronized controls to really work in-sync even when animations are on (they seem to work ok for animations off). But at a minimum if the RadDiagram had an event that was thrown when a Layout operation has finalized, we could listen to that event and call the RefreshThumbnail then.

Update: RadDiagram provides public DiagramLayoutComplete event. This event is available since Q2 2012.
