Hi Luca,
this is gettting interesting 
Altitude from Home so the Ek2 altitude but also the range finder altitude and GPS altitude are all available.
The problem with GPS altitude is that is absolute.
I could probably detect a GPS reference altitude at takeoff and use it to show relative GPS altitude from home
EDIT: this would not work see
and you’re right there’s a rangefinder value, already parsed by the script, ROTATION_PITCH_270 should be the projection pointing down. I can sure find a place for it and display it!
If you have a rangefinder fitted I’ll have you as a tester for I don’t have one yet!
Both ground speed and Airspeed seems to be both available .
docs here are misleading, should be specified that is either one or the other…
