In our installation, we believe that the navigation bar is very confusing for the end user. Our users are business managers, not techies:
That can be achieved by coping _secondary_navigation.html.haml to your app's app/view/layouts/rails_admin/ and editing in the way you want.
Isn't it enough?
Awesome - I'll try that out.
Or, you could throw some custom CSS in there to clean things up. Then you won't have to re-copy _secondary_navigation.html.haml whenever rails_admin updates it.
The sign-in language should be changeable via the rails translations.
