For which features is it advised to create UI helper classes rather than placing code in the CODE tab?

Creating UI helper classes is advised specifically for UI operations because these classes enable the separation of concerns in your application development. By isolating the UI logic into dedicated helper classes, you maintain a cleaner architecture, which promotes better maintainability, readability, and reusability of code.

When UI operations are encapsulated within helper classes, it allows developers to manage UI-specific logic without cluttering the main CODE tab. This organization helps in keeping business logic and data transactions distinct from the user interface logic, which aligns with best practices in software design.

This separation also facilitates easier testing, as UI helper classes can be tested in isolation, enhancing the overall quality and stability of the application. Encouraging the use of helper classes for UI operations supports a modular approach to development, allowing for better collaboration and easier updates or modifications in the UI layer without impacting other functionalities.
