About this extension
This Chrome extension enhances Codeforces user profiles by adding a rating-based heatmap that visually represents problem-solving activity. Unlike the default heatmap, which only counts the number of problems solved per day, this extension highlights each day based on the difficulty of the hardest problem solved.

KEY FEATURES:
🔹Accurate Rating Heatmap: The heatmap color on a given day represents the maximum rating of a problem solved that day.

🔹Quick Insights: Hovering over any day in the heatmap shows a tooltip with all problems solved on that day.
The tooltip includes:
• Problem Name
• Problem Rating
• Direct Link to the Problem

🔹 Multi-Year Support: Analyze past performance across multiple years with ease.
