Add a setting to force application language rather than use system one

[fievel]

I find it very useful when Apps allow users to override default os language settings because for some IT related stuff I just prefer English but I don't want my phone to be in English. Also sometimes translations are not good enough and being able to switch to another language can be useful to understand.

Some references about how to do: https://stackoverflow.com/questions/6414013/set-up-the-application-language-in-android-preferences#6441619

What part of the app do you want to use in English ? You can add a secondary layout that you can easily switch to in the settings. You can also enable English on your device as a secondary language. The keyboard will show up twice in the menu opened by long pressing the keyboard switching button on the top right of the Fn key.

No I thought about the application language (i.e. strings in settings UI for example)

The text in the settings are initially written in English then translated, so this might make sense to disambiguate bad translations. But the settings are not meant to be used everyday and I don't think this feature would help a lot of people. I'd prefer to improve the translations instead.
