[pengy13]

To optimize the code, you might want to consider the following:

1. Performance optimization: Check whether there is a performance bottleneck in the code and try to use more efficient algorithms or data structures to improve the speed of the program.
2. Error handling: Ensure that the code has a good handling mechanism for input exceptions, such as giving appropriate prompts or error messages when entering invalid data.
3. Scalability: Consider whether the code is easy to expand and maintain when future requirements change or new features are added.
4. User experience: Optimize the user interface, make user operation more intuitive and friendly, and provide more interactive ways and feedback information.

As for adding features, consider the following:

1. User authentication and Rights management: Add user authentication to ensure that only authorized users can access functions related to the operating system.
2. Data persistence: Save system data to the database for long-term storage and management, and realize data backup and recovery functions.
3. Multi-language support: Provide multi-language support, so that users can choose their preferred language to use the system.
4. Notification and reminder: Add notification and reminder functions to help users learn about important information and events in the system in time.
5. Data analysis and report: Provide users with data analysis and report functions to help them better understand and use the data in the system.
6. • Social sharing: allows users to share information and content in the system to social media platforms to expand the scope of influence of the system.
7. Custom Settings: Allow users to customize the system according to their own needs and preferences to improve user experience.
