Don't automatically show English translation for flashcards.
When reviewing flashcards, I find that my eyes go straight to the English translation rather than the sentence context. It would be nice if there was an option to make it so that user has to click to show the English translation. That way, the default would be for the user to read the sentence and figure out what the appropriate word is and only clicks to see the english translation when it's too hard to tell from the context. The hope is that this may allow the user to stay in his/her target language more often.
