StarDogStudio lack of autocompletion?

Support Feature Request

For example in Star Wars dB

{
    Droid {
        name
        appearsIn
        friends {  
            name
        }
    } 
}

I had to know that 'friends' and other fields in advance, should they not also have autocompletion? Just like Hasura GraphQL playground? Or is that the fundamental difference between the designs or dB used?
