Changes between Initial Version and Version 1 of Ticket #27406, comment 15

2	2	> I've been thinking of it as Customizer '''Super'''sections, I suppose for this reason. Those could be special sections that, rather than containing controls, contained sections. In the UI they would slide over and only show the sections in that super-section, as in the mockup.

4		My concern with supersections is that "super" isn't really a paradigm found in core today (AFAIK), while the paradigm of children is pervasive in WP (child pages, submenu items, sub terms, etc). For an existing pattern, perhaps the Admin Bar should be considered: the `$wp_admin_bar->add_node()` has a `parent` argument.
	4	It seems to me that subsections are more in line with other constructs in WP core. For example, posts can have other posts as parents, terms have term parents, and admin bar nodes have node parents. However, a "customizer supersection" would be a completely different thing than a "customizer section".
