Sizing and arranging notes inside and outside containers!

Hi All, I’m feeling obtuse, so please be gentle.

I’m trying to use the Map view to create notes, add notes to other “container” notes, etc. In effect, create an outline structure with notes and sub-notes, but visually. In fact, I keep trying to do this, release after release, and keep running up against an inability to arrange “sub notes” within a container so they are visible when displaying with other containers, etc.

Like this?
