Frontend And Backend Different Languages?

Hi Guys

Its possible that i can activate for the Users and Vendors only German Language Pack and for me in the backend Admin GUI i have the English Package as default?

If i go to settings --> Appearance and select --> Frontend default language: German and Backend default language: English the User can switch in the frontend and backend between both languages, but Users and Vendors should have no option to switch between both languages.

Otherwise i have to disable the English Language Pack all the time and if i switch in the maintenance mode for changes, i have to activate English for my admin changes and after that i have to deactivate it again?

You can set status of English language to Hidden. In this case it will not be available in the store-front. But the vendors still will have an ability to switch to English
