New to Linux, running Debian (if that matters), dot files are configuration files, yes? Do I need to explore each app/UI/program to figure out the possible options? Are there any universals in Linux? Across distros?
The standard is to have dotfiles in your ~/.config folder, however not all apps follow that.
Some apps dump their config files in your home, others only have files in /etc or /usr and you have to copy them yourself to modify them
