The new "Review" options introduced here are a bit awkward to use for editing.
Both saving and canceling an edit that you started from the review page bring you to the question or answer's normal page rather than back to the review page. So you need to go back twice to return to the review section.
(And that doesn't always get you back to exactly where you were if you had some items reviewed (thus expanded) before you started editing, though that might be a browser bug.)
Could this be changed to bring you back to the review page, or is this by-design to make sure you actually check the result of the edit in situ?
