Abstract: A method includes defining a placeholder widget having a property and defining a prototype graphical user interface (GUI) having an instance of the placeholder widget. The method also includes presenting the prototype GUI to a user, where an appearance of the instance of the placeholder widget is based on the property of the placeholder widget. The method further includes replacing the instance of the placeholder widget in the prototype GUI with an instance of another widget. In addition, the method includes updating the presentation of the prototype GUI using the instance of the other widget. Replacing the instance of the placeholder widget with the instance of the other widget could include transforming an instance of a lower fidelity placeholder widget into an instance of a higher fidelity widget. The property of the placeholder widget could include a textual property, an image property, and/or a graphics property.

Abstract: A user interface navigation design system and method is described in this document. In some embodiments, a user interface (UI) navigation diagram is generated. The UI navigation diagram displays two or more of the plurality of screen views and corresponding navigation relationships. A screen view is selected according to a user interaction with the UI navigation diagram. A dynamic view of the user interface navigation diagram is provided as a function of the selected screen view. The dynamic view of the UI navigation diagram displays one or more navigation relationships associated with the selected screen view. The one or more navigation relationships include non-hyperlinked navigation relationships associated with the selected screen view.
