When I drag-and-drop some selected document text within the same document, it gets moved to the new location.
When I drag-and-drop it to someplace in the binder, it creates a new document with the selection and a default title and synopsis from the text, and brings a great big smile to my face The only thing is, it does not move that text from its original document body; it copies it.
By design, or candidate for improvement? Opt-drag would be reasonable for copy, but plain drag should move it.
