Sage 9 Autocompletion in PhpStorm

Has somebody a solution for autocompletion with PhpStorm and Sage 9?

Thanks for your help.

Adding <?php namespace App; ?> to the top of your Blade should do the trick.

Thanks for your help, but this doesn’t work. Other ideas?

I Found this, but i can’t use it, because the $App Variable doesn’t exist.

Seems Sage needs something similar to Laravel and Magento 2, where it outputs a couple PHPStorm IDE Helper files so PHPStorm knows what in the world is going on.
