Theme suggestion?

ouch.

oorrrr a way to add this feature to any other theme?

there is this theme which highlights the latest post with a graphic. https://themecorp.com/themes/vidiyal/

there’s gridlock which you can see on this page or get the updated version from the designers page

But your best bet is to research. Only you know exactly what you want.

This might need php loop editing. No big deal.
