This is for https://atom.io/packages/
In github’s README view, the table of contents is clickable and will take the reader to the corresponding heading. Additionally, headings can be linked directly in a URL.
In Atom’s package display, the same table of contents is displayed as links, but the links do not work. It is impossible to jump to a specific heading using links.
The feature request is to add github’s link functionality to Atom’s.
