When reviewing and improving a suggested-edit I usually like to add in the Edit Summary box what I've additionally changed in the post, so the user who initially suggested the edit can visualize what he missed (at least what was missed under the reviewer's point of view). I usually write my name initials ("AS") after what was written by the editor, and then, add more info about the additional changes.
improved formatting; AS - fixed typos, removed "thanks", added tag x
I started doing this because of two reasons:
- The editor can learn and improve their future edits (make them more complete).
- He/she can understand better why their avatar did not appear after the edit was submitted (it helps to reduce disagreement and consequently, these kind of threads on meta).
Now, the idea here is to add a second Edit Summary box for reviewers of suggested-edits. If the reviewer decides to improve the suggestion and also to fill in an explanation of the improvements, then the two messages (editor and reviewer) would be joint in just one in a way that would be clear to the editor what was added in the review.
user 1 writes in the current Edit Summary box:
upper case in proper noun
The edit goes to the queue and there, a reviewer (user 2) decides to improve the post
In the (new) Edit Summary box 2 (which would appear beneath the Edit Summary box 1) he writes:
After the edit is submitted by user 2, the history on that specific edition stays:
user 1: upper case in proper noun; user 2: code format.
If after that, a new edit is submitted it would not accumulate with the messages from previous edits. It would start a new history message, like the current format..
I believe this could yield a beneficial snowball effect because users would learn day by day with peers. Some users come back to see if their edit was approved or rejected and investigate what they could have done better.
