I'm planning to use a markdown-to-html and of course found yours, but don't have the [TOC] functionality.
It's possible to include it?
I have no plan to add this at this time.
If I do something it'll likely be an external tool taking HTML as input so it can work with any document, not just those formatted using Markdown. I'm pretty sure there are already TOC generators like this though.
I was looking for the same thing. If not possible with MarkdownExtra directly, some references/examples on how to realize this with "MDE + (something)" would be warmly welcomed.
OK, so in case someone else is (still) looking for a solution here:
One of those should get us started :)
