When creating a new workflow, I've had a number of users cause a panic by inadvertently editing a global status (like Open, or Closed) to something else. This throws off reports, and most annoying of all, there's literally no indication that the action you're taking is going to effect things outside of your currently inactive workflow. There's not even a confirmation box.
Is there any plans to add some kind of functionality that would make it more clear that you're going to make a change with broad impacts?
There's an indicator on workflows, and schemes, as to how many projects share the setting, so you have an idea of the potential for disruption, but not one statuses.
