First of all, I would like to thank Codeforces for providing such a great platform for competitive programming.

Following some of the recent changes in the site, I found that several new features have now been added. Now, you can solve problems titled with an estimated rating. Along with this, you may solve the problems topic-wise. And if you want you can sort the problems in increasing or decreasing order of difficulty.

I would like to ask if there exists a feature too, by which we can select all 'A' headed problems or 'B' or 'C' and so on... and sort them in order of difficulty accordingly. I believe that this would help enhancing the problem solving ability.

Forgive me if this is proposed before or currently is in progress. But if not so I would request Codeforces team to implement this feature. Thanks
