Is there any flight planning software that will allow you to:
Load YOUR waypoint file,
Then
Display it graphically on the screen (map overlay showing SUA's would
be nice)
Then
Pick waypoints (by clicking on them, not making text entries!)
OUTPUT: total distance in (pick your units) , distance of each leg,
and percentage of the total distance for each leg. Optionally, allow
un-picking any giving waypoint and picking another.
Generating a task to send to your flight recorder when you're
satisfied with the result.

I have to admit I've only played with See You a little, and really
nothing else.
