The 'X' is also used to emphasize the relatedness between OS X and UNIX. 'OS X, whose X is the Roman numeral for 10 and is a prominent part of its brand identity, is built on technologies developed at NeXT between the second half of the 1980s and Apple's purchase of the company in late 1996. Use this template to prototype and design the Mac OS X Lion user interface. The example 'ConceptDraw graphic user interface (Mac)' was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Graphic User Interface solution from the Software Development area of ConceptDraw Solution Park. Smaller ones usually act as a user-input tool.'

Large widgets, such as windows, usually provide a frame or container for the main presentation content such as a web page, email message or drawing. Good user interface design relates to the user, not the system architecture.

This allows the user to select or design a different skin at will, and eases the designer's work to change the interface as the user needs evolve. A model-view-controller allows for a flexible structure in which the interface is independent from and indirectly linked to application functionality, so the GUI can be easily customized. The widgets of a well-designed interface are selected to support the actions necessary to achieve the goals of the user. Typically, the user interacts with information by manipulating visual widgets that allow for interactions appropriate to the kind of data they hold. The visible graphical interface features of an application are sometimes referred to as 'chrome' or 'Gui' (Goo-ee). Methods of user-centered design are used to ensure that the visual language introduced in the design is well tailored to the tasks.

Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline known as usability. 'Designing the visual composition and temporal behavior of GUI is an important part of software application programming in the area of human-computer interaction.
