- Intelligent Calendar Layout: A dynamic 24-hour timeline that automatically handles overlapping tasks by displaying them side-by-side (Outlook-style).
- Adaptive Time Segments: The timeline intelligently scales—hour slots expand to make short tasks readable, while large blocks of inactivity are collapsed into compact "Free Time" summaries.
- Customizable Views: Toggle between a spacious Regular mode (default) and a condensed Compact mode via settings.
- Recurring Tasks: Sophisticated support for Daily, Weekly, and Monthly recurrences with smart series management (update "Only This", "This & Future", or "All").
- Subtask Management: Break down complex activities into actionable checklists with visual progress indicators.
- Multi-Reminder Notifications: Schedule multiple alerts for any task (e.g., 30m before, 5m before, and at start) with a custom dual-wheel time picker.
