It seems some books are missing chapter markings. Revelation, for instance. The verses are numbered, and you can notice when chapters change, but one can be lost when searching for a specific chapter.
Dictionary entries are cool, but I would want the in context meaning at least highlighted, so I don't have to read the full entry and do that myself.
Overall, nice idea but it seems like a very barebones implementation that needs a tremendous amount of polishing to be useful.
