There's no mention of Taxonomies in 0.30 version of Settings in Docs.
Also within Taxonomies themselves:
admin/taxonomies in 0.30
If I create a new Taxononomy admin/taxonomies/new
then add a child taxonomy under that, I cannot associate that child to a parent.
Given that Taxonomies are replacing Scopes and Areas, Im not seeing the same functionality of Scopes and Areas under the new Taxonomies.
Also I can only associate another child as parent of a child taxonomy
