View your learnt words?
Is there a way to view all the words you've already learnt, with them being rolloverable (er, I suspect there's a better word for that) so that you can conjugate them and so forth? If not, could that be something added?
Just adding to this, it'd be great if we could add our own words. I suspect some people on here are also learning German through classes and use this website as extra practice. So it'd be good if we could add in words that we learn every week in class and practice them as well.
