Use case or problem
When folding the last heading of a file, the footnote section is currently also folded. The problem is, that those footnotes probably refer to all sections and should mostly remain visible.
Proposed solution
The footnote section could have its own fold toggle. It would stay visible, when folding the last heading, but could be folded if necessary.
Current workaround (optional)
I don’t use this workaround, but one could set a # Footnotes heading at the bottom of the note. Although the separation line does get in the way here. So one would have to remove that by CSS.
