Save this as .user.js and install as a GreaseMonkey script. It's my first ever greasemonkey script and has some page resizing problems (it doesn't), so I would welcome contributions from others.

(and I'm hoping that '<' symbols etc. don't get mangled…)

Yup, the third for loop got mangled:

for(var i=0; i < kinder.length; ++i)

Oh man - ignore the variable names, the script changed a lot in behaviour while I was hacking away.
