Portrait mode looks like it will be interesting to use. In my initial playing around with it, my first instinct was to move the red Astropad control button down out of the way. Then when I went back to landscape it was lost, off the screen. Going back to portrait brought it back, of course, but then it took me several tries to get it back where I wanted it for landscape mode. Could this be a little more intelligent? Maybe remember both of the last positions in landscape and portrait mode, and snap back to the right one when the orientation changes? At least keep it on the screen somewhere in both orientations.
Good catch! That’s a bug on our part.
I’m letting our engineering team know so we can get it fixed in an upcoming release.
