Note: This update will save the day and put Fluenz up several notches.
I've suggested changes, via email and phone, about error marking on the next text based sections. This suggestion is going to amplify the text sections nfold. Fluenz is in full control of these sentences so this shouldn't be an issue. Underline/bold, with different colors, the words per their case in the sentence. It's easy to get things confused because the Context is different than what you're reading. If I knew the cases then I would have much less issue. If I mouseover the words then I should be able to see the cases. This would be fantastic.
