I am not sure how the TOC is generated when Bibles are exported to Kindle since none shows in the Logos equivalent. As happy (very) as I am with the ability to export, I just wished there was a hyperlink to go straight to the NT if one so desires or a split TOC (names of Bible books only, leading to chapters, perhaps even verses though the latter is a bit less important). It is a bit of a pain, if you want to check something in Jude, to go back to the TOC and flip pages after pages for each book as each book is listed in canonical order with a list of its chapters.
Just a wish, a suggestion, to make a good feature even better.
