Change of title from (Configuration Management) to (App Settings Management)

It's common to call, user settings as defined in this article, app settings, and app settings, as defined in this article; configuration management. Since app settings are controlled by app end user. Configuration management "app settings" is what's done by system administrators (sysadmins/devops engineers).

So, I suggest changing article title accordingly to reflect its content.
