### Project Overview (To-Do App)
The project aims to develop a simple yet functional to-do application.  Based on the user prompt, this application will allow users to create, manage, and track tasks.  The application should be user-friendly and intuitive, allowing for efficient task management.

### User Requirements
- Add new tasks with descriptions and due dates.
- Mark tasks as complete.
- Edit or delete existing tasks.
- View a list of tasks, potentially filtered by status (e.g., completed, incomplete).
- Possibly include features like task prioritization and reminders (MVP scope to be determined in subsequent phases).

### Functional Requirements
- FR-001: Task Creation: The system shall allow users to add new tasks with a description and optional due date.
- FR-002: Task Completion: The system shall allow users to mark tasks as complete.
- FR-003: Task Editing: The system shall allow users to edit existing tasks (description, due date).
- FR-004: Task Deletion: The system shall allow users to delete tasks.
- FR-005: Task Listing: The system shall display a list of tasks, optionally filtered by completion status.

### Non-Functional Requirements
- NFR-001: Usability: The application should be easy to use and intuitive.
- NFR-002: Performance: The application should respond quickly to user actions.
- NFR-003: Reliability: The application should be reliable and stable.

### User Stories
