What is the purpose of a "UI Theme" in OutSystems?

A "UI Theme" in OutSystems serves the purpose of providing visual styles for a consistent application look. The primary function of a UI Theme is to establish a cohesive design language throughout the application, which includes elements such as colors, fonts, layout styles, and overall aesthetics. This consistency is crucial for enhancing user experience, making the application visually appealing, and improving usability.

By applying a UI Theme, developers can easily ensure that all screens and components within the application adhere to the same visual standards, leading to a unified appearance that helps users navigate and interact with the application more effectively. This promotes brand identity and usability across different devices and platforms.

Other options focus on aspects unrelated to visual design. For instance, enabling different back-end technologies or defining server-side logic does not pertain to how the application looks or feels but rather to its functionality and performance. Enhancing performance, while important, is also outside the scope of what a UI Theme is designed to achieve.
