'Conjugate' should list other tenses!
I'm learning Past Tense in Spanish, and the 'conjugate' button is suddenly utterly useless. I mostly know the common verb forms in present tense. Why is there no option to see the words in the preterite tense? I can always look the words up elsewhere, but one of the pleasant features of Duolingo was that I normally didn't have to!
If you are referring to the Conjugate option when one hovers over the word, the past tense conjugation is added when one is in the Past Tense skill. Similarly, as one comes across the skills for Future tense, Participle, Gerund, etc, those will be added to the information provided.
