What I want is a menu in the settings that is called "Global Environment Variables" and there you can add and delete environment variables that will be used globally.
I would find that handy so I don't have to look up which files I have to edit to enable global env vars every time I use another distro.
It would be really cool for new users,cause they usually hate editing config files.
The only question is,which file should be used for that function,but the file should work with xorg and wayland and all modern init systems,but I only know how to do that with systemd,you need to edit "/usr/lib/systemd/user-environment-generators/99-profile.local.sh" afaik.
