Short answer: you have to make your own.
You can start with the Express VI by right-clicking on the express VI and selecting "Open Front Panel" and click "Convert". This will create a brand new VI that is the equivalent of the Express VI. Save the VI under a new name within your project hierearchy, and then change the properties on the VI from a modal to a floating:
- Select File->VI Properties.
- Select "Window Appearance" from the pulldown menu.
- Select "Custom" option and click "Customize...".
- Select "Floating" in the "Window Behavior" section.
