In Latin, we should learn tenses
I don't see why we should only talk in present tense in latin not english we should learn ALL the tenses otherwise we'll never be fluent
I am sure that other tenses will be added to the course as it gets expanded. This is the first tree produced, and there are many posts explaining why the tree is quite short.
Given the length of the tree, I think it's better to deal with the present tense to really drill that in, before confusing things with other tenses.
The course contributors are working on expansions and this will include additional tenses.
