When building shading in the material library nodes, I would like to see broadcaster and receiver nodes to help declutter and help organize shading networks. I would imagine taking a queue from both the Mari node graph as well as substance designer where you essentially define a label name on a dot node and later, if you create a new dot node, you can choose from a list of declared names
here is a few screengrabs from the adobe designer graph
