Hi Miguel,
Your proposal makes sense to me. Have you already thought about how to
implement the UI for this?
Yes I do. I think about a keycombination while someone drag the node and a up-down value item into the node toolbar to modify the amount of "solidarity" between the node and its handles.
Have a look in src/nodepath.cpp, for example node_request(),
sp_node_selected_move(), sp_nodepath_move_node_and_handles(), etc.
You'll probably figure it out from there.
I looked in all those function and it help me a lot in my understanding of the node's move.
It seems that I got to make a node-sculpt similar function except that I got to set the dragged node's type to NODE_CUSP, the other nodes act the same way than in the node-sculpt.
Regards,
Diederik
