Hopefully this feature would be useful overall – but I do appreciate that long distance remote travel with unreliable fuel sources is a pretty specific problem to my part of the world

Well.. just to back you up. I traveled A LOT in central Asia (and further…) – this feature(s) would be extremely helpful overall indeed, maybe even the most critical thing out there are fuel calculations. Even in TET trails now days this is very useful set of functionalities, since we’re constantly calculating where to exit the trail and refill and where we don’t have to.

Would be nice to have… And very well described, if I may add.
