What does the term 'application window' primarily consist of?

The term 'application window' primarily consists of panels and panel tabs, which are essential components in many software applications, particularly in those related to digital video editing. Panels organize various tools and options that the user can interact with, such as effects, transitions, and media libraries. These panels can often be customized, moved, and resized according to the user’s workflow needs.

Panel tabs serve to categorize these panels and allow users to easily switch between different sets of functionalities or tools. This organization helps streamline the editing process, enabling users to efficiently access the various resources and settings they need without cluttering their workspace.

The other choices highlight aspects of the interface that do not define the application window in its entirety. Menus and toolbars contribute to an application's functionality but do not specifically encapsulate the views and controls contained in the larger window setup. The preview screen is just one element of the interface, primarily focused on displaying the output rather than managing the various editing tools. Saving options are functionalities that can be accessed within the application window but do not define its general structure. Thus, focusing on panels and panel tabs provides a more accurate understanding of what comprises the application window itself.
