I have been in Bible studies where rabbit trails are neither appropriate or are tabled for later discussion. In others, rabbit trails are chased down until exhausted. This Bible fits this need very well. You read a scripture that regards a topic, you look up the chain on that topic, hmm, that chain refers to this scripture who mentions a person, who is that person, hmm, that was in that place, where is that? And so it goes as God uses another resource to weave our way through His Word.
