It seem that Skydemon is not correctly annotating HX airspace. I was flying west of Leipzig/Halle airspace, and during flight preparation with Skydemon I was not aware that the airspace of EDDP is actually mostly D(HX). So I did not ask, if it is active. Only post-flight I discovered that it is actually HX, as shown in the terminal chart.

I confirm we have added (HX) to the relevant Leipzig airspace names for the next chart update. Starting in the next software version, you'll also see (HX) on the map label for the airspace if there's room.
