Graceful Theme

OK, next question, which I think is specific to this theme. I’m using it as a basis to make a sort of personal “blog” (actually a digital garden, but that’s kind of an obscure term). Since basically every post will be authored by me, I want to remove or reduce the prominence of certain authorial visual elements, mainly avatars, and especially in the topic lists on the front page and in categories. Outlined in red is what I want to hide, if possible:

You can probably see why. :grinning_face_with_smiling_eyes:

Things I’ve tried:

I am also looking into and experimenting with various components to show the first image in a topic as a thumbnail. If I could replace those avatars with little thumbnails of first image in the topic, that’d be great too. But hiding them is a good start.

Thanks in advance!
