*Automatically pre-fill the edit-summary field when undoing an edit.*Add a message at the top of the edit page when undoing an edit. This gives the user some feedback that their undo actually worked, rather than just directed them to an edit page. (Unless you actually look, there's no evidence of a successful undo, which could confuse users)
