- Moved event handling logic from the Controller class to a new HandleEvents function in the Window class, enhancing separation of concerns. - Simplified the OnEntry method by removing the Initialize function call and directly initializing the editor manager. - Updated the OnLoad method to check for window activity, improving the logic for managing the controller's active state. - Cleaned up the controller header by removing the obsolete Initialize method, streamlining the interface.
