Good work, and they on looking really good.
on a slightly related note, trying to work out how to hide the right hand side panel on small screen resolutions using the default sp control which is something like
<a href="#side" onclick="return sp_collapseSide(4)">
so that on narrow screens i can get it to auto trigger but still leave the option there to expand it (so id only want the trigger called once).. cant even work out if feasibly that would be possible..
i notice that you have them hiding altogether on small screen. wonder if its possible just to call that trigger
