Actually the social icons will be on your page, they just overflow and are hidden. If you were to remove the store icon for a moment you’ll see that the icons are under the store icon. I’m working on a better design for the storefront and store header to make it so everything fits if you’re using a sidebar or full width page.
With regards to vendor ratings (stars and customer feedback) the will show zero ratings under the store name if they are activated. Even without actually getting any feedback from the customers.
