The Focus Time plugin tracks the time users spend actively working on individual notes in Obsidian. It automatically monitors focus time for each note, including PDF files, and stops tracking when users switch notes or minimize the app. The plugin features a focus time leaderboard, displaying the top 10 notes with the most focus time, helping users identify their most engaged notes. It supports both light and dark themes and offers localization for English and Simplified Chinese. The plugin aims to provide insight into user productivity, highlighting frequently accessed notes and enabling users to better manage their note-taking efforts over time.
