The word review idea is great, but without an index it isnt practical as a dictionary.
The word definitions have more depth than Word Lookup Pro but what do you do if you dont know how to spell the word? I mean we lookup words because we need clarification for its meaning. That means we arent familiar with that word, wouldnt that also mean we may not know how to spell it?
I use Word Lookup Pro as a dictionary in large part because as you are typing in the word, it gradually narrows the list of words. If Word Vault had a similar system, it would be worth the money, but until or unless it does, it just feels impractical.
