Would you consider not displaying My Approvals on a user's Dashboard if they have no service requests to review? That way, when the My Approvals icon is displayed on the Dashboard, it would indicate that there are approvals awaiting action.
we can look into this in a future release
Please consider similar logic for My Watchers. Eliminating the icons for My Watchers and My Approvals if the logged-in user has no watching service requests and approval service request will unclutter the user's Desktop.
