It would be nice if, as a footnote, Latin roots could be shown to help people see the connection between languages. Maybe even a little brief etymology blurb could be included.
I would like that myself, I have to admit, but that would be a feature for the ultra language geeks. Probably not a priority.
Personally, knowing the Latin root helps me remember new words (in English), how to spell them, and what other words are related. Also if I come upon a word I've never seen but can recognize the root, I can infer what it means. It just seems like this may help in other languages as well.
