very well-made, looks super pretty. it is not working well with some sites, though, the content won't load.

Very useful, works like a charm. It is a responsive ToC for any (properly written) website. I initially used it on Strimzi's reference for their Kubernetes-CRDs

Works as advertised

So far really well done and helpful.

I love this add-on so much you don't even know

Awesome Extensions.
