I appear to have earned a 'point' for a single review in two queues, by flicking quickly between queues:
I don't mind much really, but this seems incorrect.
That's by design, though. If you get to review a post you already edited, the "I'm done" button is enabled by default. Doesn't matter if you are quick or not. Can be an edit that's a week old.
In fact it used to be that the button was not enabled in such cases, but people complained, and it was changed. Here is the feature request: Activate “I'm Done” button in New Post Review queue if I have already acted on the post.
It happens a lot of times to me, when there are not many First posts and Late answers. In my opinion, when you are reviewing a late answer and click I'm done, the same post in First posts should go away. It seems like a bug, not a feature.
They should just filter it so we don't see posts that we've already reviewed.
Posts are already being filtered in the first queue that a user acknowledges it, so it would be simple to just filter it for that user in the other queues also. Treat any
I'm Done or any button-click for that matter as being done in all queues for that user.
If a post is completely removed from all queues, then any filtering would be reset.
You could also just exclude the Close/Reopen queues from the filtering if it was too complicated to reset the filtering, which would depend on your database structure and how you were currently handling the filtering that is already implemented.
