Hi @johnfelipe thanks for the contribution! We'll discuss some implementation details (ex: where we store the preferred language settings ? in db or local storage is fine at early stage?) and get back to you.

I'll add this PR to the open roadmap backlog for now.

Some suggestions:

1. If you have any thoughts on how we store the preference, chime in as you want
2. some files (ex: ejemplo_de_cambio_de_idioma) don't make much sense to me. Seems like misplaced files ?
3. We're using english for file names & comments, please make sure you align to our coding styles & conventions.
4. You may want to elaborate more how you want to implement this feature at higher level

Thanks!
