No. Human UI does not support clustering. There is a flaw with the way clusters execute that makes them fundamentally incompatible with human UI - because there is no way to expire / recompute part of a cluster, the entire cluster always recomputes. Human UI assumes that 1. The create window component never recomputes after initial launch and 2. It can trigger new solutions on « value listener » components. These are incompatible with clusters.
Sorry, I don’t think there’s any way to fix this. Sometimes I use metahopper’s « create snippet » functionality to create « saved configurations » of human UI components - everything doesn’t get condensed into a single component but at least you can quickly deploy pre-built configurations.
