Yes, that was my point in mentioning above that inside(“ContainerNote”) gives you aliases for only the first hierarchy level, whereas descendedFrom(“ContainerNote”) gives you all descendants, no matter how many layers down.
Not sure whether you realize that you actually can see multiple containers and their contents while working in outline view.
Here’s a simple example: What you’re seeing in this shot is actually nine different notes (all in red), which are part of 8 different containers, but you can see them and work with them all at the same time. The top level containers are in blue; sub-containers are in green.
In a map view, you would not be able to see the originals of these notes all at the same time, because they’re not in the same container. You would have to make aliases of them, either manually or through an agent (which creates a new virtual container to hold them). But outline view actually allows you to see multiple hierarchy-levels at the same time, and to expand or collapse the detail view of each container so that you can see its contents, or not.
