Description:
Allow to edit sections by name (instead of by number) and allow to create
sections with previously nonexistent names as first or last sub-section of
existing sections.
This would, for example, allow to link to generic section names on talk pages.
A template like http://en.wikiversity.org/wiki/Template:Comments could link
to a nonexistent section and the section would be created on demand.
Allowing to create nonexistent sections as sub-sections would allow to put all
responses through "Template:Comments" under a common header.
