What's the proper way to store an apps settings? For my current (and first) app I'm for now just grabbing the `$HOME` environment variable and stuff a file in `$HOME/.config/app/settings`, but this is just for local dev and testing. Once I'm distributing it through OpenRepos I'd like to do it the proper way (if there is one).
