That's a great idea. There is another point I'm struggling with:
If I carry out a review (as moderator) I'm used to closing all review comments before I send out a new revision. In a next step the reviewers check the answers to there comments. If they do not agree with my answers they are able to:
1. Reply on my answer: The comment is still marked as closed and it is easy miss this comment!
2. Add a new comment: The link to the older comments is lost!
Is it possible to implement an option or an indicator (at least for approvers) to reopen closed comments ("No, this issue isn't solved", "No, the question isn't answered" etc.)? It might also be possible to solve this issue using "Angela's" indicators...
