Markdown interprets the empty lines resulting from [[!if]] as a request
that each <li> contain a <p>. For consistent spacing in the HTML, either
the unconditional items should have blank lines between (resulting in
each <li> having a <p>), or the conditional items should not (resulting
in messy source code, and no <li> having a <p>). I think the former
looks nicer.
orders can be specified.
* `age` - List pages from the most recently created to the oldest.
+
* `mtime` - List pages with the most recently modified first.
+
* `title` - Order by title (page name).
[[!if test="enabled(sortnaturally)" then="""
* `title_natural` - Orders by title, but numbers in the title are treated
