In the Task Status section the Change Task Status: field is displayed in gray, giving the appearance that it is not an activated field. Our experience has shown that how the approver makes the approval is not obvious enough. I would like to see it displayed in a color scheme that would draw an approver's attention to it. We recently had a task that called for two levels of approvals. The approvers were not familiar with the KCM layout and found the approval experience was not intuitive.
Even better than the above suggestion would be to insert buttons that change the status (the status indicator would only ever be read-only). The buttons should be APPROVE and INSUFFICIENT. The INSUFFICIENT button would trigger a required free-form text box to be displayed that calls for an explanation of why the task was not approved. This update to KCM would be slick!
