There is value in tweaking the auto-generated corner nodes, so I added an editor, and the ability to load a saved node layout.

After doing it i've realized some better ways to do it, but anyways here's how to use it now:
There is a variable gen_mode in setup that changes if the nodes will be
0 : auto-generated or
1: loaded from a saved list
To use the editor you have to un-comment the action to enable the editor group in event 2.
When the editor is active you can drag nodes around. Right click to destroy/add new nodes. Finally middle click to put the node list into a editbox that you can copy and paste in events to load later. I made two layouts and the node loading is in events 18-19. Just clone the layout to make other layouts.
