You should also mention the use of "acá" in this article

Hola Simón,

The synonyms "acá" and "allá" (here and there) are more commonly used in Latin America. So far we are focusing on the uses of Spanish from Spain but we are planning to extend our lessons to Latin American Spanish as well, so that's something noted for when we develop that in Kwiziq, hopefully soon. 

Gracias por la sugerencia.

Saludos

Hola Ricky

We are now looking into it. Meanwhile, if you have any suggestion about any grammatical point that is a priority for you that we are not covering at the moment because it is exclusively Latin American, please let us know. We are noting down all suggestions from students.

Saludos
