This is one of the big ways that LLMs are going to change the game for UX. Your operating system is going to have some sort of 'butler', which knows all of your preferences, and the butler will go through the APIs and man files and informational dialogs of every app you use and auto-configure them.

Then if you want something to change, just ask the butler. If the app is open source and doesn't support the requested feature, the butler might even be able to code it up.
