"Set as Default Button" not keeping all state changes

That seems a bit long winded to format a button that you want to keep consistent throughout a title. It also means you have to have one already created to copy it from. Why would 'set as default' NOT duplicate everything you have set on the button? What use is it to only save some things. then default others back to system?

Should this not be a standard function?

The section in the article you have linked "Changing the Default Button Characteristics" talks about attributes, but makes no mention of it not actually copying states... so you would assume a state is an attribute of the button.

To be honest, all I can see it duplicating is the font used and the 'normal state'. So why have the option at all? I cant be the only one finding it frustrating that I can't set a default and it be as I originally created!
