Sorting per strengh in vocabulary doesn't work
When I try to sort per strength I do not get all the strong up and the weak down the list or vice versa. I seem to get random results. This is annoying to see what my weak words are and makes me doubt that "practice weak words" choses the right words for me to train.
Someone should look into this.
The sorting does work. It's just about how we group words when we display them in the sorted order. For example, we group "is" and "was" together, since they are both different forms of the verb "to be". However, your strength for "is" may be much higher than your strength for "was".
