The Checklist Progress plugin for Obsidian allows users to track their task completion progress within markdown checklists. The plugin automatically updates the percentage or fraction of completed tasks, making it easier to monitor progress. It supports sub-tasks, and can update the progress dynamically when checkboxes are toggled. Users can also enable auto-updating in live preview mode or trigger updates manually through a command. The plugin can be customized to count both checked and unchecked boxes, providing flexibility in how progress is displayed.
