TamperMonkey user script which improves user experience with CodeWars (or at least tries to).

This piece of code is a Tampermonkey user script which provides some additional per-language filtering and display capabilities, effectively making it easier for you to obtain POLYGLOT badge.

You can get the script here.

• Install Tampermonkey extension for your browser,
• Copy&paste the script to your scripts library.

• All 'available language' icons show whether you've completed given kata in some particular language. Languages are marked also in language selection dropdowns - but first go to Solutions tab of your CodeWars profile to let the script fetch/update information about your solutions.
• When you filter kata search results by a language of your choice, additional filter option appears which lets you see which katas you have or haven't completed in this language.
• You can copy content of code boxes into clipboard.
• "Spoiler" flags are visible all the time and do not dis/re-appear in a very annoying manner.
• Contents of "Solutions" and "Past solutions" views are displayed in tabs by language.
• Leaderboards: "Solved kata is default leaderboard (since "Overall" ranking does not measure anything useful). Also, leaderboards are automatically scrolled to show your score.
• TODO: Filter discourse threads by resolution status (show only resolved/unresolved).
• TODO: You can configure the script and enable/disable features.

Features removed from Polyglot as they got implemented directly on Codewars:

• ~~ "Show Kata Description" and "Show Kata Test Cases" sections can be toggled now and can be collapsed after once expanded. ~~
• ~~ Show "Translations" tab on kata page and kata tabs on "/kata/####/translations" page. ~~

I haven't checked.

• Yes.
• A race condition here or there.
• Filters do not properly reset sometimes.
• Sometimes search results may contain duplicated pages.
• Selectors, hooks and listeners used are so inefficient that your local power plant probably doubles its coal consumption.

• You are allowed to use it, unless someone authoritative (CW staff?) says you can't.
• You can modify it ONLY IF your modifications are going to bring any improvement into the way it works, AND you are going to share improved version with CW community.
• You can send all your critical remarks to /dev/null, unless it's something I could learn or otherwise benefit from - in such case, you can contact me on CodeWars Gitter channel.

I am really sorry if this code hurts your eyes, brain, or feelings in any way, but I am not a professional HTML developer and each and every technique present here (JavaScript, jQuery, TamperMonkey, CW API) I've used for the first time.
