This is a Chrome Extension that adds the problem ratings of past contests next to the said contests' box in the https://codeforces.com/contests page. [Made purely for my personal usage. Plan to get good enough at deploying JS stuff, so that I can try to get this published.]

Codeforces API requests used:

• https://codeforces.com/api/contest.list?gym=false
• https://codeforces.com/api/contest.standings?contestId={i+1}&count=10
