it would be very convenient if you could add a 3rd column alongside the 2nd column that shows the running totals, since last airport, of time, distance, and fuel burn, as opposed to values for a single leg that is shown in column 2. When leaving an interim airport, the 3rd column values start again at zero, or give us the option of rezeroing at a waypoint.
This would help enormously on long cross-countries when we must make one or more fuel stops.
If you wanted to make the 3rd column intelligent, you could add a remaining fuel info (per leg), based upon the user input for that box and/or specs for that airplane profile.
