In the dropdown for review, we sometimes have an indicator (red circle) showing that there are many reviews - and that this particular review queue needs attention.
The thresholds are mentioned in this post: How does the review-needed indicator work exactly? (current revisions). But this post was created before the queue for First Posts was split into First Answers and First Questions. (This was announced in August 2021: Review queue workflows - Final release.)
- What are the thresholds for this indicator in the First Answers and First Questions review queues?
- Are the other numbers in Jon Ericson's answer above still valid? (Have they been changed since then?)
