I use “Outline view” to navigate around larger workflows.
If when running such a workflow there is an issue then it can take a little while to find the node that needs attention. It’s effectively the first node with a red traffic light. It would be great if the user mode had an option whereby all red nodes were highlighted with a slightly larger red marker - this would help navigate to the issue very quickly. Another possible addition to this would be to highlight any “queued” nodes in some other way to indicate progress through the workflow.
