Hi Geoff… unfortunately these are not coded into the theme and would have to be done by you or whoever can do coding. The only thing is that the icons used are based on an icon font named “Genericons” and Yelp and Kudzu are not part of their selection, so you would have to find these elsewhere or create your own icons that would match the others. Overall, it would be a bit of a job to add those particular ones.
With our premium themes, we offer access to site documentation, video tutorials and timely support. Even if you have just started on WordPress, our support staff have the patience to help you create appealing sites gracefully.
