The Checkbox Time Tracker plugin adds timestamps to checkboxes in Obsidian notes, making it ideal for tracking tasks and activities. When a checkbox is checked, the plugin automatically inserts the current time, and optionally the start and end times for tasks marked as in progress or completed. Users can customize the timestamp format to include the date, day of the week, or links to daily notes. The plugin supports various styles and can omit redundant information, such as duplicate end dates, for cleaner formatting. This tool is especially useful for those who rely on time-based task tracking and want an integrated solution within Obsidian.
