As for improving the review system, it will not be upgraded soon, not earlier than the new version of the website is released, which is still under development. And light upgraded won’t change the number of displayed claims, it would be strange to expect that. The number of active claims only signals that the majority of them have been solved, and financial obligations are fulfilled.
OK thank you for explaining, at least we finally received a clear answer that new and updated review system won't be coming any time soon (if it ever comes).
I think it would be much better if you make this changes with some beta testing using real people so you can get honest feedback from actual customers.
Some members from bitcointalk forum would probably help and participate in this process.
