Add a mini content in any single note?

Can supporters add a kind of function that can reveal a mini content in any single note?( by headings maybe)

It sounds like you want to be able to collapse sections of the text. Does that sound right?

It isn’t possible now, but is something we are thinking about for the future. For now, you can collapse the note itself, and you can also add text files to the notes which contain text. That might be a workaround to include some “hidden” text in a note.
