Only the customization options are active in this state. All other buttons are disabled.

Pros: "Default" or "Restore default" buttons might not be immediately understandable. In this alternative concept, this button is removed and a new visual element (e.g.: a border) is added to the default options to set them apart from the others.

Cons: the new visual element (e.g.: a border) might not be immediately understandable either. This new element could raise a question in the user's mind: "what does this border stand for?". Also, in this alternative concept more steps are required to restore the default settings, while in the main concept the user gets there in just 1 step.
