Post teaser images?

It’s cool there’s a teaser for the text, but will art it would be awesome to be able to add a small teaser image as well, so we can add a cropped preview or a custom icon-type thing for the type of post to keep things more visual. It would especially help when sharing to twitter. That’s pretty personal to what I do but I thought I’d give it a shot by adding it here so maybe it may show up at some point as a feature (tried searching for a similar topic and couldn’t find one, sorry if it’s repeated)
