Which feature allows OutSystems developers to create reusable components?

Screen Templates serve as a foundational feature in OutSystems that enables developers to create reusable components. By defining a set of screens with standardized layout and design, developers can reuse these templates across different applications, ensuring consistency in user interface and experience. This not only accelerates the development process but also improves maintenance since any updates made to a screen template will automatically reflect across all instances where the template is used.

Module management, while important for organizing and structuring the application, primarily deals with the overall architecture and dependencies of applications rather than facilitating the creation of reusable components. Theme settings pertain to visual styles and design aspects but do not inherently promote the reuse of application logic or screen layouts. Action flows are focused on the logic and processes within applications and, although they can be reused, they do not specifically provide the structural framework needed for components like screen layouts do.
