Hi all,

As far as I remember a couple of months ago I saw a post (or comment) on Codeforces with the link for the extension that allows showing only difficulty tag for the unsolved problems on the particular problem page (like https://mirror.codeforces.com/problemset/problem/1385/G).

Could anyone suggest a link to the post, the comment, or the extension? I have tried to Google it but did not manage to find.
