I agree with the "less stuff" part. The first pass in my slides is for content, second pass is for formatting :-). For now, I did manual division of the sides. I am using both org-beamer and org-reveal (
https://github.com/yjwen/org-reveal) and ideally they would have optimized (and possibly different) slide breaks. E.g. perhaps beamer breaks 9 elements into 3 3-elements slides whereas reveal breaks into 2 slides, one with 5 elements and one of 4 elements.
I'll look around for the previous post but in the mean time I think I will stick with method 0.
Thanks,
Stephen
