I am working on some review tasks right now, checking "not an answer" flags, etc. Sometimes, I notice that the flagged answer seems to be written by the OP themselves. Ideally, I'd want to verify this, so that I could leave a helpful comment to the OP, likely to the FAQ on the definition of an answer. However, in order to do so, I find that I need to navigate to the actual question to verify that the non-answer-poster and the OP are the same person. It seems that there's no indication of the username of the OP on the question, which is also displayed in this view.
I think it would be worthwhile to display the OP's username in the question in the 10-k tools view.
