Currently you have the cross section as perpendicular to the last leg. If it is a station with a single leg, that is the only real automatic option. However. when there are 2 legs, the most common definition and the one that gets it right most often is the perpendicular bisector of the legs. This is what pockettopo, Therion and I believe Survex all use, so it would make sense to use the same as the programme they are likely to be exported to.
I really like the lines showing where the cross sections are, a real nifty feature would be to allow the user to set the direction. Guess some thought would have to be put into how the direction is exported, but I and others have used the direction you are facing in bracket after the station number, when doing this on paper surveying, so maybe this could be adapted
