When reviewing suggested edits, if one clicks Approve, another user still has to approve it before it goes live.
However, if one clicks Improve Edit, the edit is instantly applied without needing a 2nd review.
So I ask, why does a normal approve need two reviews?
Approverequires the reviewer just a single click and not much thought, whereas
Improve Editrequires actually some work and the reviewer has to think about what they do. That way the system probably prevents robo-reviewing.
