EditorWindow.ShowUtility

Description

Show the EditorWindow as a floating utility window.

When the utility window loses focus it remains on top of the new active window. This means the EditorWindow.ShowUtility window is never hidden by the Unity editor. It is, however, not dockable to the editor.

Utility windows will always be in front of normal Unity windows. It will be hidden when the user switches from Unity to another application.

Note: You do not need to use EditorWindow.GetWindow before using this function to show the window.
