I'm sure this is because I'm blind or I havent gotten that far in the documentation yet but.. the comment bubbles on the blog posts do not show (not single entries but on the actual default blog set up) Ive looked for a setting to turn them on or off and Ive found nothing.
For reference I got the theme and immediately jumped into child theme so I'm building based on TopArt rather than in the actual BigFeature Theme. If you'll notice there is no comments bubble next to the post titles. I did quickly switch to just BigFeature and they do not show there as well so its not because of the child theme issue its not showing up in the default either.

Another issue in the default and thumbnail image is that it will not work if you put in the entire url. They will only show and work if you start at wp-content in the url. Is that a bug and will that be corrected any time soon?
