listen in pratice
Love the quick practice. Please consider adding a feature to be able to listen to the words while you practice :)
Some things translate better as a phrase than as a single word. Sometimes words are translated wrong within their context. Short phrases could be better sometimes
Better context awareness
Try and show translations fitting the context. For example, if someone says 'religion has been subject to many ..' subject is translated as matière, but this phrase would be 'a été soumis à'. I suggest adding and prioritizing the longer translations
Gradually translate all words
It seems that when I click "I know this word" it doesn't translate it again the next time. But when I know a word, I want it to translate every time, with the goal that eventually all words will be translated to French, so I'm reading the entire article in French, except for the words I haven't learned yet -- which will gradually be highlighted and translated.
Increase amount of words
If possible, I'd like more words each time, as well as phrases, to increase challenge.
Different levels of difficulty
Some people might be just learning French. Basic words are more relevant to switch. For more fluent speakers, having harder words more-frequently highlighted would be great. Maybe make people take a 5 min test on install, or be able to take it anytime to test competency?
Higher translation count
This would allow the user to start out only at a few words per page, and increase until nearly the entire page has been translated. Alternatively, you could make it so correctly answering questions also increases translations.
