I LOVE my interlinears with the 'reader' feature. I am memorizing Greek and Hebrew vocab based upon word occurrence. The ability to modify the reader to a specific number of occurrences gives me confidence when reading that "I should know this word" and I invest more time parsing it. It's probably my very favorite tool for studying the original language's.
BUT: it's not available in either the phone or tablet 'app' mode. Please consider adding this feature to the app.
