This will all be available in the next Graphene release version 1.8.
Syahir just released the alpha version. So, it shouldn’t be too long before this is released to the public.

I’d remove any modifications you made… and hang tight for a week.
You could manually adjust it all via custom css… but then in a week, you would need to remove it all anyway to enjoy the benefits of the themes options.
That’s my advice 🙂
