I suggest adding an option that would place the translated words (with a parts of speech checkbox filter) right above the input language (in a smaller font and different color). Reading texts in a language you are trying to acquire with this feature is remarkably effective. Here is an image (using the results of Google translate) to show what I mean, with only adjectives,nouns,verbs enabled: http://i46.tinypic.com/2cgocio.gif thank you Google Translate team!
