Show all possible correct translations even after you entered the correct one
In some languages there are more than one possible correct translation. For example, the english phrase: - You are welcome May be translated to spanish as: Usted es bievenido Ustedes son bienvenidos
We should be able to choose in our setting English or American English. One of the things that makes America annoy me the most is their variations in language. At least Duolingo allows variants of either. I think I'd get annoyed very quickly being told to say 'mom', 'color' and so forth..
