So I go to use it - thrilled that its a single volume which solves one dead tree format usability issue. And I get started:

Surprise - mouse over does not translate the bold numbers, click does not link you to them. Well, since I know the book I know to go to the back where I usually keep one finger while I reading elsewhere.
So I turn on the table of contents, go to the back, expand the doctrinal index and of course there is no indication of the numbers...

I have to go scrolling through to find the right number And don't tell me to use the find or inline search - too many occurrences of numbers with multiple meanings ...
Oh goodie I found one!!!

Excuse me but I find this truth self-evident: A major motivation for purchasing a Logos/Verbum resource to replace a well-worn favorite dead-tree format resource is the linking ... finally being free of the 3 volume, 2 finger nature of the book. To have the primary value of the book - the doctrinal index - still a multi-finger task, loose your place task is unacceptable. At least the links from the doctrinal index to the excerpts work.
Please link the bold numbers to the doctrinal index ASAP.
