1. A computer-implemented method of displaying on a display, for selective viewing by a user, axes of computer-readable files associated with steps of a workflow, the method comprising: (a) displaying on a display of a computer system, for view by a user, a GUI comprising a plurality of GUI elements each representing a step of a workflow, the displayed GUI elements being arranged in an ordered sequence; and (b) upon receiving user input representing a selection of one of the plurality of displayed GUI elements for displaying an axis of computer-readable files associated with the selected GUI element, further displaying, in an area of the display located after the selected GUI element and before any next displayed GUI element in a direction along the ordered sequence, a portion of an axis of ordered computer-readable files associated with the selected GUI element, with a portion of the axis not being displayed, (i) wherein computer-readable files of the displayed portion of the axis are scrollable along the axis, (ii) wherein computer-readable files associated with the selected GUI element and located on the portion of the axis that is not displayed are displayable by scrolling along the axis, and (iii) wherein the computer-readable files associated with the selected GUI element and located on the portion of the axis are chronologically ordered along a timeline; and (c) upon receiving user input representing a selection of one of the plurality of displayed GUI elements for ceasing to display an axis of computer-readable files associated with the selected GUI element, ceasing to display the axis in an area of the display located after the selected GUI element and before any next displayed GUI element in a direction along the ordered sequence; whereby axes of ordered computer-readable files associated with ordered steps of a workflow are selectively viewable by a user on the display.
