    for each division, determining whether a number of items in the division exceeds a predetermined density threshold, wherein the predetermined density threshold is configurable by a user;

    aggregating and displaying at least two of the items into a single block in each division if the number of items of that division exceeds the predetermined density threshold;

    displaying the items on the ground pane in perspective view within the first display area, each item arranged at a position corresponding to the division with which it is associated in a respective second direction at an angle to the first direction; and

    in response to a selection of one or more divisions displayed on the ground pane in perspective view by highlighting the one or more divisions of the ground pane in order to select a segment of time, displaying one or more attributes of each of the items displayed within the highlighted one or more divisions on a listing pane in a second display area, the listing pane including a plurality of records each corresponding to one of the selected items, each record including displayed therein an author of the item, a brief description of the item, and time in which the item was created or last modified.
