Recently I was exploring Codeforces APIs and thought that there is a need for an extension that shows problem difficulty as well as all the contest problems links together (as usually it takes some time switching from status/submission/problem page to dashboard to select a desired problem).
So, well here it is!
With the help of this extension, one can go through any problem to any other problem easily (also can go to a problem from status/submission/hack pages to the desired problem).
You can try this extension.
Steps to follow (for the installation)
Right now I haven't deployed/uploaded it on either Chrome or Firefox but you can install it locally!
You just have to clone this repo or can download via zip and load/unpack the folder over the chrome/firefox extension (with developer mode on). (guide for chrome)
UPD2: Updated the verdict thing as well. You can enter your codeforces handle to make verdict color work!
UPD4: The extension is now live on Mozilla Add-ons. 😇
UPD5: Updated the show/hide rating thing (check the repo).
Any suggestion would be helpful!
Happy Coding :)
