Renamable Relays

I'm not sure what use that would have. Just make a relay node and comment on it?

It's extremely minor of course, but I feel like relays have two uses:

• Bridging far out nodes, in which case the source node may not be in screen view
• Splitting vectors in named counterparts to be able to better identify them

In both cases, seeing the name of the relay is important. That's why I think the little "Relay" label should be editable.

Of course, I can easily workaround it with comments, but it's a little less elegant:

For the case of bridging far away nodes, I'd actually like to see something like "remote" relays, or basically set and get variable nodes. That way you could output from a node to a setVariable node (with a name), and anywhere else in your graph you can drop a getVariable node which lets you choose from a source list of all setVariables you have added. You can add many gets for one set. Example mockup:

That's a pretty good idea, I'll consider adding something like that
