I rolled back a major edit to one of my questions today, but I found no place to put the reason I thought the edit was not appropriate.
In this case, I thought the edits would have been better if they we put into an answer, along with an explanation of why the suggestions make sense. I might even have offered to provide a bounty to the editor for providing a more up to date answer. But i have no way to communicate this in my rollback.
Or did I overlook something in the editor?
