@a_breakin_glass I believe you can use a ‘noexport’ tag.
Completely ignore the heading and its contents? Or only the heading?
If it's the first, simply type `COMMENT` before the header title. For the second option, see https://emacs.stackexchange.com/a/41685/17462
@a_breakin_glass The tag you're looking for: noexport
@a_breakin_glass Just the headlines? Or the whole subtree under that headline?
If it is the latter, you can tag such headlines with "noexport" tag (C-c C-q noexport).
well turning on visible only export works for pretty much the same purpose, though empty headings apparently count as visible
