It would be great to be able to have an Entity Template that can be used for User Created Lookup Lists that are multilingual.
For example say you want to let a user create their own list of Product Types but they want them in multiple languages. The UI would show the list in a dropdown showing the list in the correct language.
In the UI when the Language is currently English the dropdown shows Toy,Clothing
In the UI when the Language is currently Russian the dropdown shows Игрушка,Одежда
But the ID behind is linked to 1 or 2 in both cases.
