Bookends fails to properly capitalize following colons when auto-formating book or journal article titles in sentence case. For example, what should read as "A short title: A short book" Bookends renders as "A short title: a short book". This failure to capitalize the word following the colon applies both to words in the "do not capitalize" list and to those not in the list.
OK, I see the problem. It works for Title Case, but not Sentence case. I think I've fixed it (preliminary testing works), and you'll see this in 9.0.4.
