Most of the time, answers that are really comments either apply to the question (like "I have this problem too, did you manage to fix it?") or to the accepted answer ("thanks! that fixed it!").
Could we get a quick-selection for the accepted answer as well as the question?
Right now, when I click the "Convert to comment" mod command, it shows a textbox defaulting to the question. Now I have to go grab the link to the accepted answer and paste that in there instead, and I see almost as many "Thanks" answers as "Me too" answers.
Pretty please? :)
Ok, the above text was too terse I'll admit.
What I mean by the "Thanks" and "Me too" comments, the ones I want to move are the more detailed ones, like the one I commented on Jeff's answer below, like "Thanks, that nearly solved it, but I still have a problem with doohickey X, do you know how to fix that as well?" or similar.
In my opinion, the OP probably shouldn't accept the answer at that point, since the chance of getting more complete answers sinks drastically if there is an accepted answer to the question, but users do what users do.
