Nick-
Are you referring to this: http://twoevils.org/files/wiki/Rabbit-minimal.html
I still like it a lot, but I think it is more geared towards the average editor, and not the average reader. Still, I'd love to see it on the Wikipedia site. :)
I do like it, but
* the navigation bar is already fairly long. It misses important links like watch, move, upload and will get even longer when sysop links (delete, protect) are added. With lots of interlanguage links at the bottom, you will go beyond one screen size even on high resolutions, which means (I think) that the always-on-top no longer works because it isn't scrollable. * there's no logo - no identification whatsoever. As you say, that's good for editors, but not good as a standard. * it's highly CSS-dependent and will not work well in non-CSS browsers.
Regards,
Erik
