I've been in software for 25 years and I can honestly say that Skydemon is one of the best applications I have used.  Unfortunately for some reason the developers have decided to remove a lot of the extended runways from the smaller airfields.  I spoke to a (lovely) young lady in support who informed be that it's because the don't have the exact runway coordinates.
This is a really bad decision that must have come from a developer not a pilot ! The extended runways are an invaluable tool if you are in track up mode so that you cannot lose orientation, they don't need to be ultra precise BUT in crowded airspace such as a fly in they are a great tool, not for ILS but for orientation.  Nothing has been gained by removing these, a lot has been lost.
If sky demon read this, please put them back in!
