Inactivate Users - Workflow removals.

When a user is being inactivated, the system does not stop or warn the admin if that user is still listed in workflow(s). It would be great if a pop-up could come up that would direct the admin to those specific workflows to remove/replace that user, before they can become inactivated. Without this, persons can forget to edit workflow, and then it becomes a time-consuming issue to find those specific workflows that a deactivated user was a part of.
