Ability to extends profile, but override settings

[lictw]

As I understand if profile B extends A then always settings of A applied, add abilities:

1. Apply personal profile settings if they are persist
2. If there are a drift in settings when user prompt Upload then save current settings as current profile settings

Also where is all available profile settings? Is there the extends only?

I agree that profiles that extend other profiles should also extend user settings. That's the functionality I think the extension is missing the most.
