Strengthen Skills should repeat from all completed lessons
I'm learning Portuguese for about 3 weeks now and have completed many lessons. Still I'm missing a way to practice and repeat across all my completed lessons.
I expected "Strengthen Skills" would let me practice everything. But it's bringing up mostly the basic stuff again and again (I can't count how often I had to let the lion drink its milk...). The advanced lessons make only about 20% there - and a lot of stuff never comes up.
For example there's a section "Verbs: Present 1" with 10 lessons and about 50-70 verbs and I'm far from knowing them all. But most of them almost never are used in "Strengthen Skills".
Am I missing something and if not, can this be improved somehow?
