Hi Codeforces!
I wanted to share with you all some lesser-known features of the Codeforces website that will make your life better. Upvote if you like!
Complete problemset
On the contest page, there is a small button in the bottom right of the problem list that says "Complete Problemset", which gives you a page of every problem at once so you don't need to switch between tabs while solving, or just print them out in one go.
Competitive companion
If you don't want to keep creating new files containing the samples to test by hand, there's a browser extension competitive companion which will send an HTTP request to a local port with machine-readable formatted problem data and samples automatically, saving you precious seconds of penalty.
Improve recent actions and comments quality
If you have uBlock Origin or a similar adblocker extension in your browser, right click, press "Block Element" and click anything, then paste these two lines into the box and hit the "Create" button to improve the look and feel of the Codeforces blogs section
##.recent-actions > ul > li:has(> div > a:is(.user-black, .user-gray, .user-green, .user-cyan))
##.comment > .comment-table:has(> tbody > tr > .left > .avatar > div > a:is(.user-black, .user-gray, .user-green, .user-cyan))
That's all! I hope these improve your skill and give you positive deltas!
