A bunch of nightly builds later, and all of my admin content is still underneath my sidebar. This is completely unacceptable for something that's "almost a release candidate". I'd be a lot happier with less pretty coloring-in and more actually working.
This pretty clearly has to do with font size, because when I let the browser squash things down to 12 pt, it shows just fine. Except that then I can barely read it. If your layout can't even work up to 14, that's fairly pitiful from a usability perspective. What kind of vital administrative function breaks this badly when the font size is increased?
