Codeforces Team To Do List
By qwexd, 2 years ago, In English

This blog is to list common bugs/suggestions/complaints for MikeMirzayanov. Share your ideas in the comments so I can add them to the list.

  • Make offical dark mode.

  • Add discussion section for each problem in the editoral.

  • Add unrated registeration.

  • Make upvotes and downvotes changable.

  • Rename "friends" to "followers".

  • Add report user option.

  • Add the dislike button([dislikes:1]).

  • Change hacked code verdict to "Verdict"(hacked) instead of just "Hacked".

  • Problem submission syncing (i.e. if you solve a problem in a mashup or a div 2, your submission will show up in the div 1 version of the problem as well).

  • Seperate show tags and show problem rating options for problemset.

  • An option for excluding tags when filtering problems (for example, let's say I want to do some DP problems, but I don't want greedy problems that also have DP solutions to show up, or let's say I want to practice problems from a certain difficulty, but I don't want to see any geometry problems).

  • Make offical rating change predictor.

  • Allow ending on-going virtual contest.

  • Remove penalty on all samples.

  • Add personal hacking history.

  • Rename "blog" to "article", "publish", "post" or something.

  • Make the folder icon in the catalog clickable so that we can collapse certain columns while searching.

  • In Fav. Blog Entries Option, blogs should be collapsed by default so that we can see multiple favorite blogs at one time otherwise it takes a lot of scrolling to see the next fav. blog.

  • Make comment replies collapsable.

  • Paginated comments sections. (so that blogs with a large amount of comments are actually scrollable on mobile)

  • Add an Option to show only solved problems in the problemset. (not hide solved problems only.) (Because say you want to see all problems you have solved in fft.)

  • Add an Option to filter gyms with solved problems.

  • Allow removal / hidding of problems in the Last Unsolved list (section of PROBLEMSET).

  • Add "hide if participated by any of the given member-list." option on the gym.

  • Add a feature to hide tags while preparing contest in gym.

  • Allow changing profile picture to the default profile picture. ✅

    Good idea but the dislike button doesn't exist. Let's add it as a suggestion as well.

      To make the list shorter and more prioritized, wouldn't it be better if we excluded everything that has less than 30 votes ? Because it would be a chore to do (even read) all of them.

    may be an unfair statement: codeforces admins are already busy with organizing contests, cheaters, scaling (4 years ago there would be submission queue issues left and right, no longer!). Also you never hear admins bragging about it (good).

    May be a fair statement

One more suggestion: Option to show only rating of problems (like 1700, 1800, etc) while practising problems on Codeforces without the tags for algorithms/data structures to be used.

    This is so needed. When I practice a contest I have to look for a problem in the problem set in order to find its difficulty without being spoilered by tags which is very inconvenient.

      Until the feature does get updated on codeforces(hopefully) you should definitely try the chrome extension "CF GetRating". It does exactly what you need as per my understanding.

There should be an option in the problemset to filter questions based on division and question number. For example: Problem C from Div 2.

  • Remove penalty on all samples (this)
  • Better hacking system, especially Div.1+2
    • In CFR819, most of the participants cannot hack E or latter because there aren't any other participants who passed the pretest in the same room
    • In my personal opinion, usual round with short open hacking (without +100pts, just kill some solutions) will be interesting
  • Rename "blog" to "article", "publish", "post" or someting
  • Personal hacking history
  • Restrict the comment feature when the contest is ongoing
    • There are some leak comments during the contest, and it's enough to use (and should be used) the "Ask a Question" feature when something is wrong

How about an option to collapse comments, making it easier to navigate (especially) larger blogs? E.g. collapsing a parent comment also collapses all of its children.

    Cool idea and I personally really like it, buuuuut it kinda violates individual user privacy. Sad.

    However, the idea can be changed to respect privacy (ideally) by adding an user setting that works kinda like the "don't mark messages as seen" function in WhatsApp, which is two-way.

    If the checkbox is deactivated, you can't see who follows you, but also no person that you follow can see that you are following them either. If it's activated, you can see who added you and people who you're following can see that you are.

    Ofc this new idea has potential subtle "holes" and problems — anything privacy related does — but... it feels just a bit safer

what about making articles/blogs in 'Favorites' shorter, and make it click to expand.

so far it is expanded by default and when you add some things to it, it is too long to display and not easy to scroll to a specific one.

upd: my bad, just notice this idea has already been proposed here

Allow removal / hidding of problems in the Last Unsolved list (section of PROBLEMSET). Now half of this list in my case is filled with optimization problems like this and it renders the list, unfortunately, mostly useless.

In gym, "Hide if participated by me" filter exists. It would be good if we can filter to hide if participated by any of the given member-list. Good for team practice contests.

Fix source/testcases view in "status" subpage. When resizing the window, the source code pop-up stays in place, so in order to resize correctly, one has to first close the submission, resize the window, and reopen the submission.

When you highlight a Test Case in a problem, highlight its answer too. Because when there are multiple Test Cases, it's a pain to look for answer of each of them.

Give us the ability to download the hidden test data (including tests with large I/O)! It will save a lot of debugging time when we want to upsolve problems.

      The intellectual property point does not seem to be a counter argument at all. All that argument says is that codeforces has the right to choose not post test cases. It does not saying anything about if codeforces should or should not do it. You can just as easily say that codeforces has the right not to implement almost any of the other features described here, right?

Add 'hide votes' while publishing blogs or comments so these blogs and comments doesn't affect contribution.

Someone can open a new account because of fear from downvotes.

    You can do both of them.

    For country standing, you can use CF World Standings extension. This is for firefox and this is for Google.

    You can type page number from URL section of browser for moving a page.

problem "popularity":

ability to upvote/downvote individual problems. Also ability to sort problem set by this score.

reason: I'm always searching for high quality/interesting problems, and usually look at blogs like: https://codeforces.net/blog/entry/109968 https://codeforces.net/blog/entry/73405 or recommendations from friends
