I have set up Suite for a German company. With the German language files for Sugar and a little addition here and there I am quite happy with the result.
What I am somewhat missing is to set German up as the default language. If I have multiple languages enabled (German and English), English is always selected when I first load the login page. Any order in the admin languages menu has no effect.
Also, I tried to disable English altogether as my users will always use the Suite in German. If I do and have German as the only enabled language, I will not be presented with the language selection dropdown (as expected), but the Suite will be fully in English.
This, obviously, is not the most pressing of issues. But I’d be happy if it could find some kind of consideration in future releases.
