I am often writing in a German dialect, which is quite different to the normal German. But sometimes I also write normal German. I don't want to have that two "languages" mixed up. Because the app is learning new words and suggests it than in a standard German conversatin. So it would be cool to have a second German for Dialects.
I'm using the American English version for slang and the British English version for writing normal text. Being able to do this in German would be great.
