Does exactly what I need, but it is a pain to use it. Highlighting is extremely slow – it takes several seconds. The animation for color selection box is annoyingly long and also currently broken (it disappears).
It is not supposed to be so slow. Don't hesitate to post details on your configuration on my contact form : http://jgoudey.free.fr/highlightall/contact.php5 I will try to help you.
