Currently using the 'Approve' or 'Reject' button at the bottom of a User Approval email just opens an email draft with the word 'Approved' or 'Rejected' in the subject line, meaning it still needs to be processed by first level support. The 'Open Task' button takes you to the portal where you can actually approve or reject, but it would be helpful to have this direct from the email (at least as an option)
