Past tense in the tree
I'm at level 10 at this point and it feels that it would be nice to have an idea of Past tense at this point already.
I caught myself looking for Past tense reference few times already, while Past 1 lesson is so far away.
Is there any particular reason Past tense introduced that late on a tree?
I agree; also, towards the end of the tree there are 4 verb lessons in a row (Future, Gerund, Conditional, and Impersonal Verbs) which seems like a bit much at once, especially given how useful they all are, and how few lessons remain to practice them in. I definitely think it would make more sense to spread those out, and begin including them (and past tense) much earlier in the tree.
