@sue I just noticed that I can copy the workflow! 😃 That's indeed part of the functionality.
But grouping would make it possible to separate sets of widgets and label them. For instance, you can have a set with files to work on on the left of the Workflow and a set with files and links that you need to reference on the right of the Workflow. Then, perhaps when one set grows too large, you can move it to it's own Workflow while leaving the other sets as they are.
