These cube icons on the left side and arrow icons on the right side - is a visual garbage which do nothing, but distracts. We already know: Blue name - prefab Gray name - not prefab That is enough, no necessary for icon. Especially for a gray icon. I already know that it is not a prefab, no need to draw an icon near it. What about arrow on the right side, we already have "Open" button in the Inspector view No need to add an arrow next to each prefab. Maybe it is useful for level designers, but I don't need to edit prefabs so often, "Open" button is good enough. So, can you please make an option in Unity Preferences to disable these UI elements? For example there is a tool in the Asset Store https://assetstore.unity.com/packages/tools/utilities/qhierarchy-28577 which adds icons in the Hierarchy, but it have a large options window where you can setup anything. The same should be done for Unity.
