Add more "real world" pronouns
I love that you get prompted with the pronouns, and that you can choose all or one of them. But, what do you think about adding to that list with more "real world" things. For example, "Eduardo y yo: <infinitive> Obviously, you'd want to choose the Nosotros form, but it makes you think a bit harder and its a bit more inclusive of they types of statements you'd use with the language. Similarly, "Eduardo y Rita: <infinitive>" for Ellos/Ellas/Uds. There are probably a few other real-world examples for each form, but I think you get the picture.
