• Todo List: Built-in personal todo list with completion tracking
• Undo/Redo: Full state history with undo (u) and redo (Ctrl+r) support
• Details View: Expand tasks to view and edit detailed descriptions
• Urgent Task Highlighting: Toggle urgent view mode with color intensity based on task urgency
• Push Notifications: Send todo items to your phone via ntfy.sh
