Editing nested Scriptable Objects gets tedious sometimes, since displaying another inspector can interrupt your workflow.
With Inline Scriptable Objects, you can edit a Scriptable Object with a foldout UI, just like you can edit custom serializable objects. Just decorate the Scriptable Object's field with [EditInline] and you are good to go!
