Successively displaying panels in a computer user interface. A method includes displaying a first panel of a plurality of panels. Each of the panels includes different information. The computer user interface has a plurality of navigation controls by which a user can navigate to any of the panels to access its information. A first setting of the navigation controls causes the first panel to be displayed. A user input requesting access to a second panel is received, there being at least two settings of the navigation controls that will cause the second panel to be displayed. The method includes ceasing to display the first panel and displaying the second panel using one of the at least two different settings by which more of the navigation controls remain unchanged from the first setting. Methods may be used in hierarchies and in arrangements that do not form trees.
