Wow, this is already very cool, also including transparency
The pause/resume button is only available in live navigation mode, not in simulation, right? No problem, just a question.
Also the map orientation modes are cool… For mode Route overview I would propose (just as a nice to have without any priority) an additional zoom factor to be kept, either as a slider for zoom percentages from 0 to 100% or some fixed overview modes (10%, 25%, 50%, 100% zoom)
