I'm not sure what the development plans are for clusters, but here's something I did to organize a recent project that was confusing to look at:
http://groups.google.com/group/grasshopper3d/web/Cluster-Ish.jpg I drew boxes that represent clusters (or functions), and used redundant parameter components positioned at the edges of the boxes to represent inputs and outputs to the clusters. This was just a way to help clean up the mess of lines, and organize into logical chunks. So, I guess what I'm asking for is way to make clusters where you can see the insides exposed (in addition to the highly compact version of the current clusters). -Chris
