A feature I would like to see
I would like to be able, at any point in the course, to print out a list of vocabulary words covered to that point in the course. It would be helpful to me to be able to study the list when I'm not at the computer, in order to strengthen my language vocabulary.
there used to be a vocabulary list, but it is currently being reworked at the moment :)
You could just highlight and copy the words out of each lesson description and paste them into something.
Well, that's not enough to me. I wish there could be different lists: + Vocabulary (general) + pronunciation + Conjugated Verbs + "" + Common Phrases + "" + Some other lists for: Articles, prepositions, conjunctions, etc. + Main examples for Grammar Structures (according to each level)
The whole information can be found on the internet. Actually, It's useful to search it and to share it while learning. However not many people has enough time to do so.
On the other hand, the way Duolingo has helped me to practice and repeat lessons - in order to maintain golden blocks - is a good approach to what I need to learn a language. From step one to step tree: Practice, Practice & Practice. Grammar could make me improve faster, but it does not help when you think twice "what you're trying to say" and "what you are supposed to structure to say what you want to say".
I like Duolingo because It is helping me to understand and use the language automatically.
I think that would be a great feature! Alos like another member said a grammar review would be good too.
