I got my big review pile down to about 120, but then Skritter kept adding new characters. I can't seem to get it any lower - in fact it's getting bigger. Every time I'm making progress it adds new characters. Is this intentional? It makes the review bar a bit useless, as it's always 100% blue. Perhaps a scale would be helpful on the review / added bars. They often just fill up for me and I end up hovering my mouse over them to find out how many characters have been added / are ready to review.
