If you want, a plugin could be written to simplify WPs administration area. It would be easy enough to hide things that you don't want admins to see by default ("n00b" mode), useful stuff that won't break the site ("l33t" mode), and everything available ("hax0r" mode). A custom setting in the user profile would be enough to trigger it.
