thanks for letting us know.“ballistic” here means no feedback/control required. Hook to New, without the ellipses ( …), immediately creates the new document as soon as you issue the command.
The commands that have ellipses require user interaction before the new item is created (or items are created). That’s the typical macOS convention: ellipses means you need to do something else to complete the action.
We’re about to publish a blog post that further illustrates the Hook to New... folder feature.
To be clear, Hook to New … feature existed before Hook 3.0. What we have done is to support the folder case (and some other changes).
