Regularly, we find ourselves looking for a certain ticket, for example because we want to re-use a phrasing we used in that ticket.
In order to find it, we would go through the list of resolved or closed tickets. In this case, it would be extremely helpful to be able to filter on Date Answered, because usually, you will remember the date you handled the ticket, approximately.
Suggestion: make it possible to switch the filter on Date Created to Date Answered, and why not Date Modified too, while you're at it.
