Hi all,

2¢ from me: I have yet to see an example which seems like it actually needs the
ability to go “up” a level. Sometimes I need to rethink my initial impulses, but
often it forces me to use a better structure.

Considering the example used in the thread, I would think it lends itself to
something like this:

┌────
│ * General animals
│   Some text about general animals
│ 
│ ** Categories
│ 
│ *** arthropods
│    spiders and things
│ 
│ *** vertebrates
│    so-and-so
│ 
│ *** other animals
│    etc.
│ 
│ ** Overall comments
│   More about animals in general
└────

All the best,
Timothy
