By "chain-reference" do you mean click-able cross references? If so, we are working on this already! Once we firm something up, I'd like to share my ideas with you on how we plan to implement it and see what you think.
Yes, that sound exactly like what I'm referring to. And, in fact, it sounds very exciting! Man, you're really on the ball! I'd love to see what you're plans are, and would be more than happy to offer feedback.
God bless you and yours :-)
We have some special surprises in store for this kind of thing, too, once we get the basic cross-reference thing working.
