I guess that’s the art of ‘technical’ documentation … a balance has to be struck, for sure an appendix can be denser … but for some stuff it would be even less fair to bury it there alone … that’s the balance i imagine is being struck
the ‘compliment’ is freely yours to embrace if you are a true frequenter of the appendix … i was just trying to make a distinction for how the division may be formed between main/appendix i.e. key/advanced
even adding pointers could get messy, it’s not easy getting it right … but having a pointer like that or even an abridged version of the related text could be handy - no issues with that idea, just commenting on why it might be structured as it is
“Midi Notes” as a subsection title should be changed imho … unless it’s a subsection exclusively about Midi Notes (and not notes about Midi)
