What I’ve noticed when it comes to answering users is that often someone will provide an answer that seems correct but we’ll want to leave it for a bit to make sure the person asking the question has a chance to review.
What I’d really like to do is be able to mark an answer as solved after a delay of x days if the original poster doesn’t reply in that period. If they do reply before the timeout then don’t do anything (ie. leave it up to the user/mods to revisit and mark solved).
