I've been practicing French for a while, and I really like how Duolingo is set up to help me study and practice. As long as I've been learning it though, I've always been worse at understanding spoken french than I am at reading it. Could there be an option to study specifically by using only the audio versions to improve listening comprehension, rather than having both the spoken and written versions? It's great having both when initially learning, but it would be great to have the option to practice each individually.
