I just created Dig Text, a new writing standard, which allows you to read the shortest version first, and dig deeper only where it interests you. I thought about dig about ten years ago, lol, and now, with the help of Claude Code, I spent two weeks thinking it through and coding it. It’s still in BETA, so I’m gathering feedback, but I would love if you try it and let me know what works and what doesn’t. https://digtext.github.io
I had a similar thought for math proofs, where you should be able to see an overall proof sketch first, then expand on any point to see the intuition/longer proof in a hierarchical way.

((text)) and :::dig ::: tags in the demo.Marginally related on the "dig deeper" part:

Thanks for your patience, I am back from my time off.
What do you mean by preview text? Do you mean Here is some text that is shown ((and some text that is hidden))? I don't consider that as preview text, I am imagining text showing up on hover (unsure about exact design). If you mean something else, I don't understand.
Also I still have no idea how the :::dig syntax work.

I like the idea, though I also already really like classical options such as footnotes, and don't even mind footnotes on footnotes.
One UI feedback point: when expanding an item, it is currently shown exactly like the main text. I'd have preferred some form of highlighting, maybe slightly different font colours or background colour for each level, to show where the expansion starts and ends. I found when expanding an item, I wanted to read the addition but couldn't quickly identify where it ended, which made it more difficult for my brain to selectively read just the expanded part.
I used such three level bullet points style in https://www.lesswrong.com/posts/iBg6AAG72wqyosxAk/the-badness-of-death-in-different-metaethical-theories
I'm trying to find the best user experience for progressively expanded reading. Footnotes, for example, are only one indentation level and honestly most of them online are a pretty terrible experience to click on.
Footnotes on sidebars are good for most simple cases but insufficient for more elaborate structures, but you can in fact put a footnote in a footnote to get more than one indentation level.
I like the idea of footnotes on footnotes. I can see an interesting exploration in this space where footnotes (and footnotes of footnotes) appear as a bottom bar/appearing over the text. Sidebars don't work IMO as on smaller screens there is not enough horizontal space, and mobile is where a lot of text is read.
