1. fl companion and flstat do not take into account the fact that flying in a straight line is not necessarily quicker; if you need to fly around the sun, a curved path is the shortest.
2. neither flcomp nor flstat can share waypoints. this would be an awesome piece of functionality, and if you are able to implement it, would make your program very attractive. dunno how though, maybe a file you could export via skype?
It has been moved since vanilla though, that my be the issue.
However, I have only my best wishes for your success in this, and you will have a great many people that'll thank you if/when it comes to fruition. It'll make for a great economy-testing tool too, allowing the dynamic-economy mod to actually get out of the mothballs for once.
