I suggest you explore the possibility of implementing a high-voltage power line proximity warning in the Litchi app during flight (as observed in the Airdata app, but only after the flight is completed).
I believe this could be extremely useful if possible.
However, there could also be a way for the drone operator to create a warning that can be analyzed by the Litchi developer and, after verification, implemented as a hazard warning (based on flight coordinates). I imagine this would be quite complicated to implement, but it’s worth studying this suggestion. Thank you for your attention, take care, and may God bless you.
