With regards to point 6. invert macos screen colors. What is the use case for this? and more importantly why bind it to a key combo?

For example a left-right flipped screen could be needed in a rear projection setup, but I am at a loss for what you would use inverted colors for.

For reading at night it is a delight to invert colors.

Sadly on macOS 11+, Apple changed some color management so it became unusable together with the f.lux app because the warm colors become cold/blueish instead.

Unfortunately, dark mode is no proper replacement because it does not invert standard web pages.

I used to really used to like f.lux's darkroom mode for this (and coding at night - it just looks badass).
