Also, two more requests / suggestions:
 * Add a CSS class for ".pi-data" objects that defines if it has a label in it or not. I've had 2-3 times this would have been useful. I can't wait until CSS 4 so we can get a darn CSS parent selector! But until then...
 * I've mentioned this before, but I would love to be able to give specific infobox fields a "class" / "id". A) it could allow workaround for situation you didn't think of and B) sometimes a specific element needs to be stylized (example; this template on the RS wiki styles offensive "group" elements red, and defensive blue). It's very awkward to work around, and (at least on desktop) being able to define an id/class would fix most of the small design issues I've had with it.
