1. A computer data processing system comprising: a computer readable memory configured to store informational objects having property identifiers associated therewith; a display configured to display the property identifiers of the informational objects organized within a plurality of groups, each of said groups described by a characteristic of the property identifiers of the informational objects; a processor coupled to said computer readable memory and to said display, said processor configured to execute computer executable instructions to: present on said display at least some of the property identifiers of at least one of said informational objects in a first scrollable area of said display; present on said display, in a second, independently scrollable area of said display, at least one of said organizational identifiers that describes those of the property identifiers of the informational objects presented in the first area of said display; and upon scrolling of said property identifiers presented in said first area of the display, dynamically update the at least one organizational identifier of the property identifiers of said informational objects presented in said second area of said display, said dynamic updating being processed so that: when the scrolling of the property identifiers of the informational objects presented in the first area of the display enters a beginning of a new group of said property identifiers of said informational objects, said new group described by a new organizational identifier, said new organizational identifier is rendered in said second area of said display so that said new organizational identifier is visibly displayed in said second area of said display adjacent any visible organizational identifier of a previously-entered and still open group of said property identifiers of said informational objects that includes said new group of said property identifiers of said informational objects described by the new organizational identifier, and if there is no visible organizational identifier of a previously-entered and still open group of said property identifiers of said informational objects, said new organizational identifier is visibly displayed by itself in said second area of said display; and when the scrolling continues past an end of all entries of said new group of said property identifiers of said informational objects described by the new organizational identifier to exit said new group such that the entries of said new group of said property identifiers of said informational objects are no longer visible in said second area of said display, and said new organizational identifier of said new group of said property identifiers is removed from said second area of said display, while any organizational identifiers of previously-entered groups of said property identifiers of said informational objects remain in said second area of said display until they in turn are exited; thereby to provide continuous automatic dynamically-updated display, in said second area of said display, of at least one organizational identifier of said groups of property identifiers of said informational objects.
