Hello everyone!

I'd like to share with you a helpful extension I have been working on CF Round Filter.

CF Round Filter helps you filter rounds by division (Div 1–4, Educational, Others) and highlight solved or attempted problems so you can focus on contests and problems that match your skill level and track your progress efficiently.

Features :

• Toggle Div 1–4 and Edu rounds in seconds.
• Color-coded problem cards with visible ratings.
• View progress and history for any user.
• Hide solved problems to focus on the next challenge.

Notes :

• Some problems exist in Div1 and Div2 rounds at the same time, they will only appear in the Div1 card.

You can download it here: Chrome

To use it, you need to be on Problemset page

If you find any bugs, have any comments or suggestions please let me know.

Hope you like it and consider sharing it with your friends.
