Methods and computer systems for document authoring

Methods and computer systems are provided for authoring documents. In one implementation, a computer system is provided that comprises an editor for editing a UI document, a pagination engine for paginating the UI document, and a pagination display for displaying a paginated document representation with respect to the UI document. The editor may be interfaced to the pagination engine so that the pagination engine paginates the user interface description document while being edited for a plurality of device categories. Further, the pagination engine may be interfaced to the pagination display so that the pagination display displays a paginated document representation for each device category with respect to the current editing status of the UI document.
