User blog comment:Sarah Manley/New Editor Scheduled for Sitewide Release/@comment-1373334-20110907233332

Source mode editors require the previous and standard layout. There is absolutely no reason that it can't be a preference setting to remove. Seeing as how this redesign is completely unnecessary, using the "maintaining two versions is hard" argument is not a valid reason to disregard a large portion of the most-advanced, most-involved, most-content-creating core userbase.
