I think your link has the smart cover "gap" that the OP said he hates. He's looking for on like Apple sells for the iPhone but as he said, giant.
I for one agree with you. However, very few companies make accessories that actually use the smart connector. If a person wanted to use one of those few options then they wouldn't be looking for a case that covered it.Why would any vendor make a case that covers up the smart connectors that is specific to the iPad Pro?
