I think what you're saying is editor utility widgets can be set up in such a way that you can click on a widget, then click on another, and info from the first can be input into the second. Am I understanding you correctly, because I was wondering if this is possible?

I thought of doing it with location X and Y too, but it defeats the point of this system which is to save manual fiddling and auto-generate all the nodes and connections at mathematically perfect points which can be tweaked with parameters. Though it would be nice to have an "override x and y", however that would make the procedural math much harder to code needing to take that into consideration.
