The idea is:
It would be really good to have a way to group multiple nodes in a collapsed view, similar to sub-workflows and be able to save the grouped nodes as modules that can be reused without having to constantly rebuild individual nodes in separate workflows. The modules should also be available in the side menu, like the nodes side menu.
My use case:
I have a webhook that responds with $execution.resumeUrl and then waits for a response. If the group node is available in the list of nodes, users can quickly reuse previously implemented nodes. An added benefit of adding this feature is that users can visually see a simplified view of the workflow, yet still can customise the workflows. I know this is another take on the sub workflow, but it’s slightly tweaked to simplify the workflow and make it reusable.
