## Description

CSES Enhancer is a lightweight browser extension designed to improve your workflow on the CSES Problem Set. It helps competitive programmers stay organized, track progress, and solve problems faster without unnecessary friction.

✨ Key Features:

• Direct Code Submission
Paste your C++, Python, or Java code directly into a built-in editor on the submit page, eliminating the need to upload files manually.

• Custom Problem Notes
Add personalized notes to each problem (e.g., "Segment Tree", "DP", "Graph") to remember key concepts and approaches.

• Star / Bookmark Problems
Mark important or challenging problems with a star to revisit them later.

• Live Stats Panel
Quickly view your total solved, wrong, and remaining problems directly on the page.

• Custom Sorting
Sort problems by number of solvers (difficulty) or keep the default CSES order.

• Local Storage
All your notes and starred problems are stored locally in your browser and persist across sessions.

🔒 Privacy-Friendly
This extension does not collect, store, or transmit any personal data. All information remains on your device.

🚀 Built for Competitive Programmers
Whether you're preparing for contests or practicing DSA, CSES Enhancer helps you focus on solving problems instead of managing workflow.
