Exclude fields that are already selected from the code completion list

Actual behavior:

Currently, regardless of what fields already exist in the selection set, all fields are shown in the IntelliSense.
For example, if I have already selected the field title, when I go to the next line and enter t, title is still shown the list:

Expected behavior:

I would propose excluding the fields that have already been selected from the code completion list; so that in the example above, title is not suggested again to the developer.
This would obviously be much better and it would give the developer more convenience because each time they only see the remaining fields, and they would not be suggested the fields that they have already selected.

In addition, it would also be nice the code editor gives you a warning whenever you select the same field more than once.

it makes sense to query a field multiple times with different aliases and args.

i would recommend to just order the unused ones to the top and/or mark the used ones with an indicator e.g. *

You're right, but only if the field has arguments. Otherwise, why would you want to select the same field more than once with different aliases?
