Clicking out to close a dictionary popup only works if you click empty space within the layout center. This is annoying. On a wide monitor, most empty space is on the sides (where clicking doesn't close).

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.
