I'm amenable to the colour and the icon changing, I just had to do *something* with it.
(icon = wrench.png from Fugue, background colour is #f3f3c8)
As you can see I haven't yet pulled it to every button, but you get to see the before/after shot of it, as such.
@Nao, yes, so far I have actually modified index.css because it's in a bunch of places, and I wasn't sure whether mana.css would be loaded in those places or not. I haven't done any analysis or anything on figuring out whether it's smaller or not yet. It may be that we move it back to mana.css where I originally had it...
