Menu to display above posts on mobile version

Hi and thank you for creating such a beautiful and simple theme, it’s wonderful!

I’ve activated it on my site and am just seeing what it looks like on my iPhone. It works fine but the Top Menu (navigation) appears right at the very bottom, so I see latest posts, then side bar content and then right at the very bottom, the navigation.

This doesn’t make much sense to me and could confuse visitors to the site. Is there any way I can get it to display the menu options under the site title and before the latest posts?

Thank you for your help,
Sarah
