In a software application, what is an area that allows customization of various UI elements called?

The term that refers to an area in a software application allowing customization of various UI elements is "Workspace." The workspace is designed to provide users with flexibility in how they arrange tools, panels, and menus to fit their workflow preferences. It enables personalization of the interface, where users can position various components according to their needs, making it easier and more efficient to work on their projects.

A workspace typically encompasses elements such as panels (like the Properties panel or Library), toolbars, and other UI components that users may show or hide based on their requirements. Through this customization, users can create a more streamlined and tailored environment for their specific tasks.

The other terms, while related to software interface concepts, do not specifically capture the notion of customizability of UI elements in the same way. For example, a toolbox usually refers to a collection of tools for performing certain actions, a dashboard may display summarized information or key metrics, and a control panel often pertains to settings or configuration options rather than customization of the interface layout itself.
