I am interested to track the progress in "my neck of woods", that is to roughly estimate how many posts in the queue match the filter I selected (FWIW, my current filter is "primarily opinion-based" and according to Shog, recently queue had 6,345 posts that match it).
Taking into account that I may use filter settings for various close reasons and tags, what could be difficulties to show / refresh this kind of stats? Could there be performance or UX or other problems?
Note similar idea was mentioned in an answer in How to make close-review queue less thankless
It might be helpful if you could see how many questions there are in the queue that fit your filtering options.
That way a reviewer might focus on a seldom used tag with a chance of completely emptying the queue for that tag.
Another answer pointing to this is in Fuzzy the number of questions in the close review queue...
Counter proposal: why not show how many questions are awaiting review in my part of the site...
My question differs from above in that I am specifically interested to learn about what could prevent this from getting done.
