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.
