Hi, thanks for the reply. Silly me, you're right regarding the input going automatically to the active app/window. The dark mode helps battery, that's true, but we still have a risk of AMOLED burnouts. If you could, that would be great! From the coding point of view it would be something like: full screen + all black/black top layer/canvas and to exit it a phone button (power or maybe a vol+power combination?) or mappable input device button press?
