Since a few weeks or months, I see geo-referenced Taxiway-Charts for aerodromes in Germany.
I remember, we discussed this some time ago.
I am not sure whether this is Feature of the DFS-subscription or if it Comes from SD itself.
Anyway: it's a great improvement, congratulations.
Idea: Switch to Taxiway-Chart from approach-chart and back dependant on the GPS-Speed. Taxi is normally slow, therefore Speed can be a good Trigger for choosing a different chart.

I appreciate the auto zoom feature showing more and more detail as one approaches teh destination airport. However, switching to a completely different chart is a different matter to me. Once you are landed it is safe and easy to select the taxiway chart manually since you are already sitting on the ground. I realize that there probably won't be a unanimous opinion on this one. Personally, I don't care for too much automation that doesn't offer a clear (to me) advantage.
