This would like is a night mode. A switch that would make it possible to vary the brightness of the screen at will as you need the needs or time of use. Without having to install a skin, then change it again the next day 😉 This is how I understand these requests 😉
Yes, and integrating it with the Windows option to automatically invoke a night-time dark mode would be preferable (and is something that I have previously suggested - though personally I woud prefer to manualy switch betwen dark and light modes - something which iStripper currently supports albeit a little awkwardly) but it is not what the regular requests have been for which, as far as I can remember, has always been for a simple "dark theme" (see, for example, the tltle and the initial post of this thread).
Some people just want a simple, permanent, dark theme. I used to configure most of my software that way - though, oddly, I have never bothered to do so with iStripper.
