And finally (honest!) probably the easiest to implement, a "submit & comment on" button added to the approval nodelet. Which upon submission displays a comment submission form. Helas I'd probably go for this one myself (as fun as the others might be ;-).

UPDATE: Currently to do what is proper one must; click okay, hit submit, wait, click comment, enter comment. This would change the procedure to; click okay, hit "submit & comment on", enter comment. It amounts to a redirect because a different button was used. Social engineering + convenience.
