At a minimum, if autoration is not an available option, the orientation should be user selectable manually. There are just too many times when I need that control without having to shut the whole app down! It's just minimal functionality -- can't be that hard to implement. Although this app has a number of nice features, if I can't change the orientation without having to reboot the entire app, I will stick with FlightPro.
In the meantime, there should be something in the manual(s) and FAQ's that explain about starting the app in the orientation desired. I went through all that material, the release notes (which said it's been a feature since ~March) and the app itself, up down and sideways, and found nothing until I got here. Requiring a complete app reboot is far from intuitive.
Other than that, so far I like the app.
