This would be helpful for those fluent in Greek and Hebrew who wish to memorize in the original languages. If you added this feature, you would be the only app that offers such a helpful way to memorize Greek and Hebrew texts. I recommend the text of the nestle-Åland 28 for the New Testament and bibles Hebraica suttgartensia (Leningrad codex) for the Old Testament.
I second the Biblia Hebraica Stuttgartensia! Please also make the Textus Receptus available!
Logos software offers memorization of any version of the Bible that is in your library.
