About

Enhance your Codeforces practice with persistent, problem-specific notes. CFNote integrates a clean, distraction-free text editor directly into the Codeforces sidebar.

Features:
Contextual Saving: Notes are automatically tied to your specific Codeforces handle, contest ID, and problem index.
Cloud Sync: Your data automatically synchronizes across all your devices using Chrome Sync Storage.
List Indicators: Easily spot previously annotated problems with visual markers right on the main problemset tables.
Central Dashboard: Manage, review, and delete all your notes from a single extension popup.
Offline Backups: Export your entire note history to a clean .txt file with one click.
