Suggestion: Vocabulary list
It will be very helpful if duolingo generates the list of vocabulary you have already learnt. And possibility to create flash cards to revise vocabulary. Thanks.
Before I started in with Duolingo, I used Babbel. Build up a vocab of over 3,000 French words in the free Babbel app for Android before the poor thing collapsed under the strain. This has helped me considerably in working with Duo whose strengths are in dealing with working with syntax and grammar. Can I suggest this as a stopgap until Duo finishes its rennovation of the vocab wing.
