I occasionally (would like to) use headlines with empty titles, e.g., when a tag in some headline already provides all necessary information, and an additional title would duplicate that. Are empty headline titles meant to be supported? If yes, then there are at least two bugs. On #+BEGIN_EXAMPLE ,* A ,* :B: ,* C #+END_EXAMPLE org-element-parse-buffer and org-match-sparse-tree make the second headline have title ":B:" and no tags. Best wishes Sebastian
