I went Pro solely because of the Difficult Words.
I like to choose my own words, and review them until I feel I know them.
I don’t want to relearn them, or write them, and I like to choose when I have learned them.
Why has it been changed?
Not only am I wasting time relearning them, writing them, and having to put them back into the Difficult Words list, but on the app I’m limited to 4 words per session!
