As someone who uses no customization in the header, I've got to wonder...

What customization do you use, is it really, really vital, how does it break everything, and is there really no way to work around it?

I'm genuinely curious - it'd be too easy to dismiss customization as "a clock and a dropdown in a dropdown". What do you customize?
