Thank you very much for your awesome work!

I'm using the code your offer here:

How to tweak this code to make it even darker? (Completely dark to make it simple). I tried to change several parameters, but without success.

Sorry for the late reply. It is better to do this by playing with the brightness of the monitor. Jinzim published a new class. using it maybe i update.
In fact, it is possible to do this right now. But it does not work with the blue light filter.
