I’m teaching myself how to build my own themes on WordPress. I’m using the latest version, and using the underscores starter theme. My question is, how can I make the default “Latest Posts” widget show post thumbnails too? I’m trying to create a tube site style “latest uploads” page – without using plugins since they have too many features that I don’t need and I don’t want to bloat my website with unnecessary code. I’ve been trying to edit the core code for 2 days but no luck so far. All help is appreciated. Thanks!
