While DataMaster provides an inspector built-in to the Catalog view window, the ability to dock it is limited. If you want more flexibility, you can use Unity’s native inspector and dock it into the Catalog view window.
In the Cataog view window, use the toolbar to disable the
Show Inspector button.
Drag the Unity inspector into the Catalog view window to dock it. Like all Unity window’s you can dock it anywhere in the window that suits your style.
