I'd like to see a more detailed quiz report at the end. Instead of just a "5/6 verses correct" dialog, a listing of the verses that were incorrect. Just a good way to see which ones need to be worked on.
Also, a note of thanks for the great tool, and thanks for making it across all Linux, MacOS, and Windows. It's great to be able to use the same program no matter what OS I'm in and be able to share the verses file between them.
