Sorry to be frank, but it would be smart if I could choose between staying open or closing automatically. Even better, if it remained open until the beginning of taxiing, closed before takeoff and opened at the end of landing.
To me, nothing you said about auto-close makes sense... I play with many monitors and having This Black menu on my screen doesn't make any sense, since it doesn't disappear in windows mode, but it stays completely black. That doesn't make any sense
And from what I read here on the forums, a lot of people think like me...
In the next update, you could put a button in the settings and let us choose whether we want it always open or not.
My best regards
