Without being able to change amount of elements per row depending on viewport width I don't see this picking up.

Good point. I actually don't understand its behaviour in regard to viewport width. Also, there are actually no media queries used in the CSS file.

Pretty trivial to extend it.

Pretty trivial to write it all from scratch.

width and media queries do that.
