A newbie like me typically wants to look up conjugated verbs in the dictionary, since I haven't learned enough about verbs yet to figure out the root. Couldn't you in an automated way figure out that I'm entering a conjugated verb, and then look up the root?
Also, given the root, how about showing all the conjugations?
You could also do this on your verb conjugation page.
Thanks.
