[Autoblog] Issues with featured images, subcategories and sources

I have a news aggregation website called Nyhedregn.dk, and it’s supposed to work the same way as the website Newsnow.co.uk basically.

I’m specifically talking about one-click link titles with featured images and visible sources. If you check my website, you'll see that I need subcategories in order to use the post filtering option on the homepage + subcategories in the navigation menu.

Featured images have also been a real pain for me, I can't even get your feed to show images: https://premium.wpmudev.org/blog/feed/

Unsure if Autoblog can do what I need, please advise.
