a little playing around with this cute new addition.

* make the box appear faster; in general, anims should be kept to around .3s
* experiment with a mouse-over trigger; known it is possible to re-show it accidently if you click on the top pixel of the button, but i'm not sure i like this feature enough yet to bother to fix it ;)
* paint an svg in behind the label; we need a real svg for this. i'll bug the artists about it ;)
