Carrot: Codeforces Rating Predictor & Ranklist Enhancer

'Carrot' is a dynamic Chrome extension built to enhance the experience of Codeforces users. It provides real-time analytical data for both active and finished contests through updated ranklists. For active contests, Carrot predicts the changes in ratings, calculates the required delta to rank up, displays them in new columns, and offers real-time calculation. Finished contests feature the final deltas, enabling users to view the rank changes. Carrot also presents a unique 'performance' column that showcases the rating at which one's delta would be zero. With the freedom to toggle columns as per user preference, Carrot ensures an organized and relevant data display. Despite running entirely on browser-based communication, it delivers high accuracy with only minor exceptions due to the new rating system.

It is not working properly from a few months , here is the message it is showing on my device-> "Could not establish connection. Receiving end does not exist."

Best extension ever made, only time it does not work is when codeforces api is down during contest. if you see error 403, it means cloudflare is blocking this extension.
