About

Contester has many useful functions for a competitive programmer, which will make his life much easier when solving and sending problems on the codeforces.com website:

1 - Submer. The function of quickly submitting code by pressing Ctrl + S and selecting a file and compiler* by pressing Alt + S.
2 - Problem Viewer. The task menu. Quickly switch between competition problems without visiting the "Problems" tab, and also highlights verdicts in different colors and automatically updates the points for the problem, taking into account incorrect submissions.
3 - Ranker. Displays your ranking without visiting the results table, gives a quick link to "Friends Standings".
4 - Profile Colorizer. Colors the link to your profile with the color of the rank, shows the rating when hovering over it.

Also added are small functions, such as auto-update of the offline page, saving the compiler without sending and running the code in the "Custom Invocation" tab by pressing f9.

All functions** can be configured in the pop-up menu.

The extension is currently under active development. We would be very happy to have an active community that will send us bugs and ideas for new features. Telegram channel with my extensions: https://t.me/mrChestsExtensions.

*The compiler is selected depending on the file extension. The required extension may not be there, in which case please write a review, comment in the telegram channel or a letter to the personal messages of my codeforces account mrChest.
**Except for small ones
