Prevent mid-flight black screen by adding screen-off warning #602
Description
By default, the HDZero2 goggle turns off the screen after a while. The user is warned by sound and screen dimming.
If a user is unaware of this feature (as I was), they might ignore dimming warning and sound (as I did) and then get a black screen mid-flight (as I did).
Please implement a textual warning indicating that the screen is about to turn off, so the user can react and prevent it from turning off.
P.S.
I did mange to land safely, but it was a close call.
