I just posted the same post, I hope they are working on it. Right now, you can use anchors as a table of content... If I'm not mistaken, you need to highlight the line or heading that you want your visitors to see as a table of contents, and you make it as an anchor.

Great site, I got the same problem actually... I want to create categories that will be the pages on the menu, and it's just a mess... I hope support will help me with that soon. Great site man!
