Which of the following can you do with the Live UI tool?

The Live UI tool in Pega is primarily designed to facilitate the real-time editing of user interface elements during application development. By using this tool, developers can directly manipulate the layout and appearance of UI components without navigating through multiple design interfaces.

Changing the position of a UI rule is one of the core functionalities of Live UI. It allows developers to drag and drop components or adjust their placement immediately on the screen, providing a visual and interactive way to fine-tune the user experience. This capability enhances efficiency, as developers can see changes as they make them without needing to refresh or redeploy the application.

Other options reflect functionalities that are outside the purview of the Live UI tool. Adding new data elements involves underlying data modeling, which is not part of the UI editing process. Similarly, creating backend logic pertains to rulesets and business logic that define system behavior, which Live UI does not address. Generating reports on user activity relates to analytics and reporting capabilities, again not within the scope of UI management. Thus, the focus of the Live UI tool specifically on UI layout changes makes it crucial for enhancing user interaction design effectively.
