I recently found that iOS allows adding a ☀️ icon to the control center. It's called "Reduce White Point" which is a bit technical. What it actually does is make the screen darker than the brightness setting allows. When I have a migraine attack, I sometimes still can and want to use a screen. But even the lowest brightness setting can be too much. So it would be great to see a feature like this in GNOME! #AccessibilityInFreeSoftware
