Yeah I agree, lack of visuals sometimes makes it hard to tell what's happening when a field moves as fast as it does in GS. There's a github page called Awesome3DGS [1] that is updated whenever there is a new paper in GS. It helped me a lot when I was getting started.

Most papers also have their own project page that showcases their contributions or demo their project as well (:
