Two problems when I open "Words" and sort them by "strength":

• The verbs are listed in random forms instead of infinitive, as one might expect. A confusing example: "nada". Looks as if "nothing" is meant, but a closer examination reveals 3rd person singular of "nadar".

• Fine, I see some words are overdue. I'd love to tick the checkboxes, press a button and practice phrases that contain them. But there is no checkboxes and no button. I did "the dumbbell" thing, but the bloody words are still "overdue".
