+List all tasks including their subtasks in a hierarchical view.
+
+This command shows all tasks with their nested subtasks, providing a complete project overview.
+
+## Execution
+
+Run the Task Master list command with subtasks flag:
+```bash
+task-master list --with-subtasks
+```
+
+## Enhanced Display
+
+I'll organize the output to show:
+- Parent tasks with clear indicators
+- Nested subtasks with proper indentation
+- Status badges for quick scanning
+- Dependencies and blockers highlighted
+- Progress indicators for tasks with subtasks
+
+## Smart Filtering
+
+Based on the task hierarchy:
+- Show completion percentage for parent tasks
+- Highlight blocked subtask chains
+- Group by functional areas
+- Indicate critical path items
+
+This gives you a complete tree view of your project structure.
