Very useful, but some remarks

I use it really daily. I like the update and esp. the option to export separate words with definitions.
CONS: the Favorite list became clumsy to use. I have a long one. After viewing a word, there is no back button, you slide it to so back, but it will return you to the top of the list. Now you have to scroll all the way down again to find the next word.
