Lookbook show only hovered node

I think this is something I might be able to hack on my own, but I’d rather see it be an actual feature. We use LookBook to show parts diagrams with callouts for each part the customer can order. In this case, the part names can be long and complex, so having every node display when any one is hovered is very cluttered. We’d like a way to only show the node that is actually being hovered over.
