From October 3rd, 2014 to February 16th, 2021, 50% user give 5-star rating, 50% user give 2-star rating. for Github Toc chrome extension.
It works and injects a TOC at the top but unfortunately messes up the styling of the headers in the document. Also, the TOC cannot be collapsed or not moved to the side resulting in large documents to first show a huge TOC.
Thanks! It is very useful to me!
