我还能指出其他问题，例如，控制器的客户端验证、可适用工作流程和动态策略模式在什么地方？

I could point out other issues, for instance, where are the client side validations, adaptable workflow, and dynamic strategy pattern for the controller?

在客户机控制器类中实现API方法。

Implement the API methods in the client controller class.

例如，一个胖客户机控制器可以提供对图标的拖放控制，而瘦客户机控制器却不会。

For example, a rich client controller may provide drag and drop controls for ICONS, whereas a thin client controller would not.
