I'd like to add some additional features to the heading of my site, but the theme doesn't

Hi,

I'd like to add some basic social icons to the top of my site, but the theme doesn't seem to permit this customization.

Also, I don't seem to be able to swap the plain-text site title for my actual logo? Which seems silly. I must be missing something from staring at it too long.

Thanks in advance for your help! Thrilled with my subscription so far!
