Site Title in the Middle of the Page

Hi there,

in the example site the Site Title is positioned between the Menu items - is that also a requirement ? As you may need to reduce the number of menu items for that.

No, it's not a requirement. I will keep the menu items below and the site title above.

Thats easier.
Add this CSS to your site:

.main-title {
    text-align: center;
}

You can change the font size and weight in Customizer > Typography
