I’ve just posted a change to the links page that is somewhat of a work-in-progress and, as such, needs just a teeny-weeny bit of work before it’s quite as useful as it might be. Anyway, I’ll introduce cookie-based persistence to your check-box preferences very soon and will resolve the problems in Opera. I the meantime, have yourselves a fine weekend!
Update Still not complete but I’ve added a JavaScript function to re-assert your selections when you return to the page. In addition, I’ve hidden the check-box and used a
label to allow the heading to be used as a toggle. Next step will be cookie-based persistence.
