Maybe something like this already exists and I haven’t been able to find it. But if they don’t, could we have sort of fake/empty nodes that don’t do anything. This would allow us to manage our wires a little better.

Rather than having those two wires flying through the graph causing clutter I could re-route them on the outside.
