Great point, I had forgotten about SM’s neural review factoring in links. Inter-note links aren’t really a big “thing” in SM for the most part so I never got much out of it, but given Obsidian’s link-centric focus it would make sense to add in some of the related notes as well. Perhaps with a slight weakening of the selection algorithm so you don’t get all related notes for every note selected for review. One thought is to only select those that are linked and have not also been reviewed within X period (presumably slightly longer than the primary note being selected) and possibly also taking into account things like link density in the secondary note.
