Note: This suggestion is related to the Node/tree Clipboard topic, but perhaps its different enough to warrant its own discussion.
I would like to have the ability to duplicate a node and its subsidiary nodes. I like to give my notes some structure, so I have often found myself creating a template that I may use multiple times in one tree. Right now these need to be replicated manually, a process that seems unnecessary. It would be great to have a clipboard function that allowed me to easily copy a node (and its subsidiaries, if desired) and paste it.
This would require some way of selecting which nodes get added to the clipboard (perhaps SHIFT+clicking the nodes - a common method used for selecting multiple items in other applications).
