Maybe a simple checkbox is sufficient, defaulting to un-checked: "Set as Default for all Examples".

I understand that "Set as Default for all Examples" seems simpler, but I think the more technical term might be broader; Inspector is designed to be used outside the scope of examples as well.

How about a checkbox: "Set as Default for all Domains".

I think it is not possible to define localStorage for all domains. I think the lack of information in the names caused a misinterpretation, so I had the idea of adding an info button to provide more detailed information about the options.

There was a difference between origin and domain and I thought localStorage was stored by domain, so I updated it to be more accurate too.
