Clean and pleasant interface! I'd suggest a possibility to create your own "decks", so that users could have more flexibility, as well as reduce the manual workload off of you. I'd personally be interested in Finnish and would love to add words that I am still learning.
De qualquer jeito, o projeto tá top. Mandaram bem demais, boa sorte!
