Recently, I noticed a change in the submission workflow on Codeforces. Previously, when opening the submission page directly from a problem, the problem code (for example, A, B, C, etc.) was already selected or filled in automatically. This made the submission process very smooth:
--> Read the problem.
--> Code the solution.
--> Open the submit page.
--> Upload/submit the code.
Now, the problem code often needs to be selected manually. While this may seem like a small change, I find myself frequently switching back to the problem statement just to confirm whether I'm submitting for A, B, C, or another problem. This is especially noticeable when:
- Solving multiple problems in a contest.
- Working through old contests.
- Using separate tabs for coding and submissions.
- Returning after a break and forgetting the exact problem index.
Of course, manually selecting the problem is not difficult, but the previous behavior reduced friction and eliminated a small source of mistakes. My suggestion would be to automatically preselect the current problem when the submission page is opened from that problem statement, while still allowing users to change it manually if needed. I'm curious whether other users have noticed this change and whether they find the previous workflow more convenient.
Blogger's Review: This UX suggestion is quite practical, especially in high-pressure contest environments where minimizing steps can significantly enhance a coder's efficiency. It would be great to see Codeforces implement this improvement!
