It would be nice to have a date/time stamp in the workflow setup to show the last time the workflow template was saved (not in the grid, but when you're actually editing the workflow, maybe somewhere in the area below)

Also, it would be helpful to have a pop-up reminder to save the template when you click the "Back to Workflow List" button, just in case. After a while, that red text above blends into the background and is not always noticeable if you've been in the workflow templates for a while.
