Include a "Language" setting in the mobile application.

Currently, the application's language is controlled by the device's language settings. However, as is the case in a lot of popular applications, the mobile application could have a "Languages" settings which could help the user switch languages from within the application.

This could serve as a huge boon for multilingual people (like myself), who tend to keep their device language as English since not all applications are compatible with their language of choice, but if given a choice would want to access the application in another preferred language.
