The biggest issue I’m facing with blueprints is the wires. It’s fine when you have just a few nodes, but once you have more than a few, it can become a (hay)wire nightmare. Especially when dealing with local variables as you can only have one node, so all accessing has to go to one single node.
So I thought it’d be cool if you could create knots on wires to rearrange and connect wires without going all the way back to the node.
Blender uses this in their node setup and it works wonderfully. Optionally, we can also set the knots to have hard edges vs vector edges which also goes a long ways towards cleaning up certain nodes.
