Presentation descriptions are provided to an operating system of a computing device to present outputs associated with the applications in an organized and intuitive manner to the user. The presentation descriptions provide the operating system with information about the structure and meaning of the output element. The task of organizing at least part of the output elements associated with applications is delegated to the operating system. The operating system analyzes the presentation descriptions, and organizes the output elements associated with the applications at least partly based on the presentation descriptions.
