Ah, I see, that’s unfortunate. That’s generally a real problem with tools that try to edit existing writable config files.
I really want to make a distro which is built on top of basically a GUI-first (at least for most general configuration) NixOS kinda thing, where you both have to go through the tool but it also doesn’t limit you in what you can do. That’s a huge endeavor though especially to get it right :^)
