User blog comment:Sarah Manley/Updates to the Editor Redesign/@comment-1393830-20110703234212

A couple of peeves having used it for a little now.
 * There is no buttons to lead back to wikiactivity/recent changes. The only way to get out of the edit window is to hit publish or hit back, neither of which will take me to recent changes, the page I want to go to if I was only grabbing some code off a page or decided against the edit I was going to make
 * The edit window cannot be customized. Aside from some personal js that I added such as the quick preview function not working in it, other MediaWiki customizations also no longer work. At Bleach Wiki, we had notices on the edit page that warned users of our spoiler policy and the like. These are gone in the new editor.
