Thanks for your reply. I think a global option would be useful because I mightn't know in advance whether I'd need slides for particular headings or not. I'm thinking of a use case where I have produced a long LaTeX article and have selected certain tags to do so, and I would build a beamer presentation to brief it out by adding a :briefing: tag to a subset of the exported article headings (so the beamer slides are more concise).

I've gone through the beamer manual but haven't seen any way of doing
so.  However, it was a cursory look so maybe you could check it out more
closely (the manual is >200 pages long...).

I wouldn't recommend allowframebreaks as a global option, in any case.
IMO, that leads to sloppy slide design, but this *is* my opinion only!
There are times where it is needed but it is generally better to be
conscious of needing it.  Just my two ¢...
