You might have seen some new reports popping up in the Other Reports section of the Reports Dashboard.
These are some canned reports that have been added to all customer accounts. These provide a quick overview of the status of workflow requests, the ones that are pending and completed. You can also see an aging report that displays the number of days each request is pending, with whom and the number of days since the request was initiated.
Take a look and keep your workflows fast and efficient!
