Instead of formatting line items in each module with a color for past periods, and current or future periods. I believe there should be a global setting allowing users to have all past periods shaded gray and current/future periods as another color. It would be nice to be able to select these colors rather than a standard color. Some may prefer to have 3 colors with one for past periods, one current period, and another for future periods. Allowing user to set opacity percent for these different time groups may be helpful as well.
