"The classic editor will be updated with clear links to the mobile and desktop previews, in an effort to help editors easily see how their articles will be seen by users on different devices. This tweak will also see the return of edit summaries that can autocomplete (as it is now a single line input)."

Save for the main page of a wiki as it's still similar to what it was (with some spacing errors), I'd rather have back the previous preview option. 13:05, March 4, 2015 (UTC)
