I’m was just on the fence of going the other direction: Consolidating book annotations that are currently in individual notes to one note per book like @mikeschmitz example above.
My motive for that was to make the graph more usable. As it is today, since atomic notes from one book are tightly linked to each other, the graph is becoming increasingly hard to “read”.
But I’ve also foreseen the problem Mike illustrates with backlinks on block level missing.
What @ryanjamurphy suggest is an interesting thought. Having a plug-in that could “explode” markdown exports from Readwise into separate notes, with the quote from the source as a markdown blockquote and the annotations as standard text below and then rebuild a consolidated book note with transclusions with all individual notes would be really useful, I think!
Something along those lines for the individual notes:
—-
tags:
source: [[book note with all other notes transcluded]]
—-
> quote (page number)
