User blog comment:Sarah Manley/Updates to the Editor Redesign/@comment-1997905-20110718153005

After using the new editor for a while, I'd say its a big improvement over the old RTE. It isn't, however, an improvement over source. Scrollability is a big concern, flipping back and forth between the preview and the page lags massively, can't navigate anywhere else while editing, and categories are stored in the sidebar that you aren't likely to use for anything else. If you use the RTE, it's great, but if you use source it's just an inconvenience. I don't mind making this default, but there should be a preferences option for using the MediaWiki editor. Like Monobook, we don't care if you don't add any new features to it. It's MediaWiki's default, and that's why we want to use it.
