Currently, in the Day tab, you see the timeline in the top section and in the bottom section you see on the left a breakdown of the individual tags assigned in the order they were assigned with durations, and on the right, these same tags summarised into total duration for the period selected.
Down in the bottom-right section's statusbar, it shows the total time for all tags which includes both billable and non-billable.

My request is that this statusbar total be modified to show total billable, total non-billable, as well as the total of these combined. This would make it easier to see total billable time from this screen, instead of having to manually calculate it, or go to the timesheet tab.
