Hi Caspar,
I think, the following would be a simple and consistent behaviour:
Simple dragging should remove the previous parent, and add the dropped on
node as a new parent.
Ctrl+dragging should add the dropped on node as a new parent but should not
remove the previous parent. (On Mac Cmd+dragging)
Of course, if you decided not to include this feature, I respect that.
Cheers,
Miklos
