Thirty or forty years ago, it would perhaps have been cumbersome for a document writing app like StarWriter, WordPerfect or Microsoft Word, to insert a dynamically-self-updating table of contents. But these days - it is usually (or always?) not much of a hassle to burden LibreOffice with also updating a ToC when edits are made. So, while I'm not suggesting we do this by default, I am suggesting we add support for an always-in-synch table of contents: It would be an opt-in toggle, and only available when the ToC cannot be edited manually.
