User blog comment:Sarah Manley/New Editor Scheduled for Sitewide Release/@comment-93604-20110907211151

Try removing categories in source mode in a wide window (editing preferences) from any of the pages listed here: http://community.wikia.com/index.php?title=Special:Categories&limit=500 - It is not possible. Also, pages with rich text editing disabled force one to edit in source mode. In those cases one can't go to RTE mode to get the right sidebar. There is no right sidebar in source mode in a wide window. See: http://community.wikia.com/wiki/Category:Potential_copyright_violations - this page has rich text editing disabled.
