PingObject generally highlights an object without selecting it. It lets you quickly find assets in the project. Why do you want to select the Prefab? A selected prefab now just shows an Open button in the Unity Inspector. If you’re editing an FSM on a prefab you already have it open... is it to find the prefab to drag it into a scene? Do you want it to close the prefab stage? You can see what a simple Select Prefab option would do now by manually selecting the prefab in the Project view - is that the behavior you want, or something else? Sorry if I’m being obtuse, just wrapping my head around what’s useful in this new workflow...
