When using the noheaders feature, it has to be added in manually on every page. I think a good idea would be for when noheaders/1/ is used, it saved a noheaders cookie, which stops headers & footers form loading without having to re-enter. As long as noheaders is functioning, it will say "NOHEADERS ACTIVE [Exit NH Mode]" below the ads, with "Exit NH Mode" being a link that clears the cookie.
