@omz , just when you thought I couldn't be anymore annoying 😁
Sorry one thing more to mention.
I think it would be nice if in the site-packages directory, you had another directory called something like 'App Files' or 'Config' or something like that. And then by convention apps that are saving config info , create a directory inside your special folder and store their app specific config info inside their folder.
Just as a convention, they don't have to of course
