Do you want to have multiple color schemes that you can quickly switch between? If you have already built the configuration with a color scheme, the second time you build it should take much shorter. Changing between a fixed set of color schemes is also a proposed feature for Stylix: https://github.com/nix-community/stylix/issues/447

Similar tools you can check out are Tinted Theming, Pywal16 and Catppuccin.

I haven’t noticed a difference between server and client side decorations when using GTK apps, but it’s nice to have uniform server side decorations for apps that are not GTK

Those on Nix can also use Stylix which implements the same workaround

What I meant is that in order to share these games, other people would also need such a device or at least an SD card reader, which most people don’t. It’s not because of you.

It would be pretty cool to share games using SD cards like that, but there would hardly be anyone to share them with.
