If you were to design a MediaWiki skin, what would you change from the default (Monobook) layout?

MediaWiki is the open-source wiki software that Wikipedia uses. It can be skinned, and can vary quite a bit, from the default Monobook skin (< a href="http://en.wikipedia.org/wiki/Main_Page?useskin=monobook" rel="nofollow"http://en.wikipedia.org/wiki/Main_Page?u…/a >) to the upcoming Vector skin (< a href="http://en.wikipedia.org/wiki/Main_Page?useskin=vector" rel="nofollow"http://en.wikipedia.org/wiki/Main_Page?u…/a >) to wildly different custom skins like the one the They Might Be Giants wiki uses (< a href="http://tmbw.net" rel="nofollow"http://tmbw.net/a >). If you designed your own skin, what would you change from Monobook?
