    Abstract: This invention permits users to conveniently examine functions, applications, data, and other parameters for different periods of time. A region of the graphical user interface is provided to which other icons may be dragged so that the function represented by the dragged icon returns to a prior state or is extrapolated to a future state. By storing the previous m versions of a file, application, database, etc., where m is user selectable, the user can review prior versions of that file, application, or database without explicitly having to track those versions. The graphical nature of the present invention provides a significantly more intuitive way to manipulate the time.

    Abstract: This invention allows the user to rapidly determine the interrelatedness of icons on graphical user interfaces. Upon selection of an icon, for example in a drag-and-drop interface, all other icons to which the selected icon may be related are graphically highlighted. This provides a user-friendly, dynamic, visual catalog of interrelated icons. A scenario matrix contains information that defines the relations among the icons on the graphical interface.
