Would be great to see another sub-tab in the MYWORK approvals area that show 'WORK I HAVE APPROVED". in this tab would show the history of items you have provided feedback on or approvals. All license types should have this (not just Workers).
If you use task approvals, you can build a report that shows you all approval steps that include a certain person and whether the approval was rejected or approved. I do really like this idea as well however.
