I think it would be great if when an approver clicks on the link within the template and the window opens with the description and listed conversations that the list of all approvers be shown along with their status  ie) pending approval, denied, approved.  Should also show any comments they may have made

 

Also an approver should be able to add a comment without having to approve or deny a request.  In other words they should not have to deny a request if all they need is additonal information before they can make decision on the request
