Yii2 Support, PHPStorm plugin

Does anybody know how to configure the views, so it can find them?

It seems the aliases come from the “Directories” configuration:

Then in the Yii2 Support plugin configuration, we can add “Themes Path Map”, now I don’t understand that. So far it seems the “Path Mask” is the real path in the system, and @app denotes the project main dir?
And the “Alias” is taken from “Directories” configuration?

Please enlighten me, how this should work. I want to use it with self-made packages in vendor folder.
But it never finds the proper path to the view.
