When I'm dealing with a client that has dozens or hundreds of workflows, and they interact in some way, it would save a lot of time if there were a Date Published column, so I can do a quick scan of all of them and see if any were changed just before a problem started.

The way it is now, I have to take a best guess from searches of activity in Designer, and then click each workflow, and then click 'View Version History' and then scroll to the bottom of the list.
