There's one feature that I particularly liked on another custom ROM that allowed me to double tap the status bar at the top of the screen to turn off the screen/display. That way I could tap once anywhere on the screen to turn on the display (a feature which GrapheneOS already has, luckily) to check the time and see if there are any notifications and then double tap the status bar to turn off the screen when I am done. This would minimize the pressing of the home button and therefore less wear and tear on it. I'm hoping this reasonable and VERY convenient feature will be available in a future update! I'm using a Pixel 6.
