To view footnotes at the end of each section, you can use the org-footnote-section
option in your org-mode file. This option will automatically place footnotes at the end of each section, rather than at the end of the whole document.
To enable this option, you can add the following line to your org-mode file:
#+OPTIONS: org-footnote-section:t
You can also customize this option in the org-mode customization interface, by going to the "Org" group, then the "Footnotes" subgroup, and checking the "Footnotes at end of section" option.
In addition to enabling the "org-footnote-section" option, you may also need to enable the "org-footnote-auto-label" option, which will automatically create labels for your footnotes. This option can be enabled in the same way as the "org-footnote-section" option, by adding the following line to your org-mode file:
#+OPTIONS: org-footnote-auto-label:t
Once you have enabled these options, your footnotes should be placed at the end of each section, and should be automatically labeled and linked.
If you are still experiencing issues with footnotes not being linked or placed correctly, you may need to adjust the "org-footnote-define-inline" and "org-footnote-auto-adjust" options. You can find more information about these options in the org-mode manual, or by consulting the org-mode customization interface.
