[UPD: 22 July 2020 -- v.1.2] Codeforces Enhancer — Chrome Extension
By agul, 9 years ago, translation, In English

During several years Codeforces users created useful userscripts that collected significant amount of fans. Tonight I merged a couple of popular scripts into one Chrome extension Codeforces Enhancer.

Brief description of features:

Colorize standings by used programming language

Based on userscript by yak_ex (http://mirror.codeforces.com/blog/entry/1871).

Multiple rating graph comparing

Based on userscript by yak_ex (http://mirror.codeforces.com/blog/entry/1743).

Hiding solved problems in the Problemset

Based on userscript by pablo.aguilar (http://mirror.codeforces.com/blog/entry/4357).

You can download the extension at the Chrome Web Store: https://chrome.google.com/webstore/detail/codeforces-enhancer/ocmandagmgmkcplckgnfgaokpgkfenmp.

Source code on Github: https://github.com/agul/cf-enhancer.

I will be happy to receive feedback and suggestions :)

Can you give options to "list of how many people participate in a contest by country wise and standing by country wise"?

could you provide options for user to enable and disable features ? I liked graph comparison feature but colorizing standings by programming language did n't catch my eye. So i would like to enable graph comparisons and disable colorizing standings.Please try make some changes regarding that in next update.

By the way i liked this extension.It's good.

How can I make this extension work on Opera, since Opera uses Chromium engine?

    Actually you can simply open source code (colorizeStandings.js) of the extension (in your browser folder) and change colors to whatever you like. You can even delete some languages, etc.

By making the standings colorful, you mean making it blue with a tinge of pink :v

Hello there. This is a great extension. Many features all in one place. But the multiple rating graph isn't working. This is related to a chart update in the website. I have fixed the code. Can you please replace the code of this feature in the extension to make it work. Thanks in advance.

You can find the fixed code here.

P.S. I commented on it in the author's article as well.
