I would like to be able to separate billable and non-billable time within the lists. I work with billing for hours worked, but time reports need to be separated from billable and non-billable. I see that the list has the filter for tracked time, but more filter fields need to be inserted where we filter only what is billable. The weather reports are also very basic. I would like to be able to make graphics with the total time x what was invoiced.
