Why isn auto renumbering of footnotes turned on by default?
Org mode has a very robust footnote mechanism allowing for a variety of types of footnotes. With some of the following footnote notations, auto-adjust may be either irrelevant or undesired: • Automatically numbered • Footnotes with custom labels • Inline footnotes In addition, org mode can be customized to place footnotes either at the end of a document or at the end of the outline heading in which they appear. Users who change this setting while editing a document may be disconcerted to find all of their footnotes rearranged automatically.
