Hi devs, I've updated http://dev.xwiki.org/xwiki/bin/view/Design/ImproveWikiAdministration with the status and current implementation of the new administration app. Please review it and provide comments and suggestions before I make the first patch. The css stylesheet are in development, so are the selenium tests. There is also a small but I couldn't fix so far, althouth I have a workaround in mind.
