I have not yet adopted Dendron as my PKM manager but I am instinctively drawn to the hierarchy model.  Then today, I ran across this tweet:  From @studio100a to @codexeditor. "I mapped the index of a book. Then created hierarchies from the map."  My question--is this a viable strategy to implement in Dendron to develop the structure for the placement (and naming) of notes of various kinds (fleeting, literature, reference, permanent) in a digital zettelkasten?  Has anyone attempted this or successfully implemented this kind of approach?  TIA for comments.
