Looks like what I wanted, thanks! Took me a bit to figure out how to write an openrc service for its daemon but now it works

I just have a ~/txt directory with mostly plain text files in it, sometimes .org

Cool, this was easy to install. I don’t see “Rando” menu option however, menu is same as before

upd: thank you for help on discord, it worked! Needed to use windows installer via wine. This is a better solution than sledgehammering the whole desktop brightness

For Deus Ex in particular there’s this https://www.cwdohnal.com/utglr/ Even though it has GammaOffset variable in config I never got it to work (nothing happens).

Yay, gammastep is just what I needed!

gammastep -O 8000K -g 1.5:1.5:1.5

I maxed what I can but still too dark. I mean maybe what I want is going to break the “intended look” of different games, but I don’t want them to be physically painful for me to play.
