New function: save words and sentences - what do you think?
I think it would be very useful to be able to save words and sentences you encounter in the lessons. Like when you stumble upon a word/expression that is difficult to remember you just press the save-button and the word is added to your personal list of words worth revising again. Technically speaking I don't think this would be a lot of work, and it would definitely help people achieve their goals in the long term. It's more effective than completely redoing older lessons you've already worked through and you know 80% of - that's too boring for most of us isn't it? And then imagine you could print out your own vocabulary list with all those words you were struggling with... I'd like to hear about your opinions, duolingo staff and users :)
