If an approver presses "decline" by mistake there is no way to go back and approve the request without starting it over completely. If there are multiple layers of approvals this can be rather frustrating for everyone. I think, if we could have the option in the task tab to "Verify" that would send it back to the approver with a comment that would help. So the email back to the approver would have the APPROVE/DECLINE buttons again with a personal comment about why it is coming back.
