Your concern raises a more important question on headline numbering across individual pages. It may or may not be desirable to have fall-through numbering of headings. I can see how some variants of multipage export may choose to number headings either using continuous numbering across the pages or to restart the numbering for each page individually. Moreover, things like :headline-offset or citations may or may not need to be computed across the pages. :headline-offset should probably be limited to a single page, for example. For citations, multiple options may be considered (think about numbered references that may either be global across the pages or local, per-page). To address the above concerns, we will probably need to introduce global :multipage setting alongside with multiple others (like settings controlling headline numbering). Further, we will need to make sure that the splitter runs last, after normal split functions, so that nothing can interfere with it. But for now, let's do minimal required change that does not introduce too many new things and simply modify `org-export--annotate-info' as the following (setq tree (org-export-filter-apply-functions (plist-get info :filter-parse-tree) tree info)) (setq info (org-export--collect-tree-properties tree info)) (when (plist-get info :multipage) (setq tree (org-export-filter-apply-functions (plist-get info :multipage-split) tree info))) (when (plist-get info :with-cite-processors) (org-cite-process-citations info) (org-cite-process-bibliography info)) :multipage-split and :multipage are new global export options. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
