A relatively minor thing, IMO, but I suspect not trivial to correct:

Using Jude as an example, citations of verses in books outside of Protestant canon (e.g. Esdras or 1 Enoch) give pop-up "links" within the current book. But it's very random. I'll use bold to show which numbers are actually highlighted as links.

For example, in the comment for Jude 1:6, the citations for 1 Enoch 10:11-14, 18:15-16, and 21:3-6 bring up Jude 1:11-14, 1:15-15, and 1:3-6 respectively.

The citation for 1 Enoch 10:4 brings up Jude 1:4.

1 Enoch 22:11 brings up Jude 1:22.

1 Enoch 54:6 and 84:4 are not highlighted or linked at all.

Wisdom of Solomon 17:17 is not highlighted or linked at all, but 17:2 brings up Jude 1:17.

I did know about this issue, but it was a tradeoff, we either have implicit references detected or not. If we have them, then there is the possibility that we get false positives as it were.
I have asked the team for suggestions on how we can improve the situation.
Thanks for raising the matter.

To me, it's not an urgent matter. It would certainly be ideal if the links all worked properly, but unless someone has a brainstorm about how to implement a fix quickly and easily, it doesn't seem like a high priority.
