In that thread I was looking for Pedigree collapse but that report doesn’t do that. How I can find them in Gramps (massively, not by just selecting one person and running deep connections gramplet)? Does another report or gramplet do that?
Yes, try the “Ancestor Fill” text report. Here is sample output:
