Agreed! I wonder how it will work if I have to reinstall, I guess I git clone my flake from the install CD and use that instead.
For Qt themes, I had Catppuccin working on Arch but I haven’t found a way to apply it. I tried Stylix (kde.enable = true does nothing for Dolphin or nheko), the official Catppuccin flake (dropped GTK support, sets QT_STYLE_OVERRIDE which breaks nheko). I know it’s possible to theme Qt apps because I’ve had it working before, but I can’t find any info on how to do it with NixOS that works…
