A new option when writing long posts to include a navigable table of contents. Use headings in markdown format (# before a single line heading for heading1, ## for sub heading2 beneath that etc).
How to Use It
You can add a Table of Contents (TOC) in the menus like this:
Sometimes posts can get quite long, and this encourages the use of headings. Also makes it easy to navigate to a specific part of a post using the clickable link. On desktop check out the area to the right. On mobile you’ll get a wee thing to click at the bottom if you like.
Yes of course, although a TOC is only applicable to a new topic post, so replies don’t count.
