TOC/alternative for static HTML exported from tiddlers?

[Madeline]

I use TW5/node.js to maintain our family/household information.

For emergencies, I need a more portable format like exporting tiddlers to an HTML file. But not having a TOC would make it hard to navigate an HTML file with over 350 tiddlers.

I've spent a few hours scouring tiddlywiki.com and this forum for potential solutions. After all that, my best idea is to filter/export groups of tiddlers into multiple HTML files rather than just one. In the top-level tiddler for each group, I would then use the list-links macro to link to the remaining exported tiddlers in the group (e.g., <<list-links "[tag[tag for the topics in this grouping]]" >>). So, if my top-level tiddler is Medical, list-links would display the titles for medical insurance, each person's medical records, etc. 

I'd still like to jam everything into one file if I could, though... So does anybody have suggestions for plugins, macros, simple JavaScript/other programmatic solutions, or other tools I could use to generate something approximating a Tiddlywiki Classic format?

Thanks! Madeline
