A benefit of creating an Application Properties page for each application you develop is that Application Properties allow a developer or admin to make changes to an application’s behavior without modifying application artifacts. Application Properties are system properties that store configuration information for a specific application. They can be used to control various aspects of the application, such as feature flags, default values, thresholds, or URLs. By creating an Application Properties page, you can group and display all the properties related to your application in one place and make them easy to access and update. This way, you can avoid hard-coding static data in your application code and make your application more flexible and maintainable.
