Instanced Noise Nodes
Implement something similar to a docked node (possibly greyed out, or with another appropriate symbol) that is an 'instanced' copy of a noise from somewhere else in the graph. Would help to reduce node spaghetti from reusing noises for optimization which get all over the place. If you change a parameter in one of the instanced noise, like scale, disorder, whatever, then it would update all of the instanced noises that are tied together in this way. Hope that makes sense!
