True Dark Mode
I have a new Lenovo Carbon X1, 11th generation, with an OLED screen. To keep power consumption down, it's important for screens shown on such screens to mnimize white pixels. It's also true that on OLED displays, their black pixels are "blackest black" in the sense that they are blacker than on "standard" LED screens. So, I'd like to be able to switch to a true dark mode at least when running on battery, as I'm doing right now, or when a passenger in a car, as I am right now. It also would help to avoid annoying the driver with light from the screen.
A true black mode would allow me to view my black-text-on-white-background pages as white text on black. Is there already a way to do this that I don't know about? If not, is it a reqsonable thing to post as a feature request?
