Table of contents
Would it be possible to add a table of contents feature?
The user would type something in the note such as [toc] or {{TOC}}, and the renderer would generate a table of contents with clickable anchor links that lead to specific sections.
For example, in MacDown:

I would find this feature extremely useful for longer notes.
I'm personally interested in this only for macOS (since I use Android), but it would probably make sense for iOS too.
this would most likely rely on upstream https://github.com/commonmark/cmark/issues/78
but it's possible to use macOS to do this...
you could create a Service using something like https://github.com/jonschlinkert/markdown-toc and then setup a right click menu or hot key to generate the TOC from selected text and append and replace that text. and it would work in any app.
Thanks @gingerbeardman - interesting this is such a long-standing issue. I guess we'll have to hope that commonmark will eventually settle on a solution. Otherwise perhaps this could be implemented as some kind of post-rendering step in fsnotes. In the mean time there is the workaround you suggest.

I also ask you to vote on Prouct Hunt and Reddit, it will help in spreading:
