[Mannshoch]

Is your feature request related to a problem? Please describe.
Switzerland has four official Language. Many times, Products has their Information in several languages on the product.

How should I enhance a Product. Im from the German speaking part of switzerland. Sometimes I have A Product on the app tht was filled by a French or Italian Speaking person. should I:

• add only the details from the French description
• could I add missing details in German because OpenFoodFacts has a translating database and Products are automatical translated
• should I add all details again in German

Describe the solution you'd like
I wish that my app in every way only show me product details in my language and may ask me If a Product is not translated.
The ingredient Database do auto-load translated ingredient list and I'm able to correct if Data has changed in my prefered language.
