According to the latest newsletter I've read, SkyDemon dev team is happy with the product and no feature is missing. I agree with that and I find it fantastic to fly with.
However, I can say that French pilots are missing one feature that is available in other softwares which is the official VFR ICAO IGN map 1/500000 (eg. VFR Next / Garmin Pilot).
I'm not sure it's feasible to add it in the software, but I mention it as SD competitors usually offer it. Quite sure as well that SD dev team thought about it.
