This app is a shortcut to launch Netflix and it's in the regular app section. It doesn't actually move anything it just creates a shortcut.
The reason this is better because it leaves the Shield Hub alone. I use Gamestream to play my PC games on my Shield so I didn't want to disable it.
Use http://atvlauncher.trekgonewild.de/index.php to create your own app shortcuts.
I also think two rows for the Leanback Launcher isn't enough anymore. It takes forever to scroll all the way to the right to access some of my less used apps. I think four rows and much more customization should be added to the Leanback Launcher.
