In any case I got a demo build of the expand / collapse modular pipelines feature here: http://kedro-viz-fe.s3-website.eu-west-2.amazonaws.com/KED-2517/expand-collapse-modular-pipeline-fe/?data=spaceflights if anyone wants to play. The final version will have some more changes but we are hoping with this change we can de-clutter the pipeline visualisation as well as encourage people to build pipelines in a more modular manner.
