Up next, user configuration, after which you can choose no GC routes (fastest), lo-res (every 1000 mi, default), or hi-res (every 200? mi, slowest) rendering.
I was wondering whether there would be a way to make the GC routes look even better. Is there maybe a function that displays a smooth line through the calculated points instead of straight lines between points? I would imagine that this would give quite a good approximation of the GC route even with only few actually calculated GC route points. Maybe an initial heading would be needed for this, too though.
