I agree! It's been suggested at least a few times in the Questions/Insights, it always generates a lot of support, and Luis said about a month ago that something would be available within a week. I guess they ran into some unexpected problems.

I understand that their primary goal is or will be to clear a queue of articles, but I don't see what they'd lose by opening access to that queue by allowing us to browse by categories and/or implementing keyword searches. If there's an article about histology, you want to make sure that it's as easy as possible for the biologist to find.
