1. You should be able to just set the `title` variable.
2. Reading the files manually seems like an ugly hack. The list.tmpl
template does not get the posts directly (although changing that
wouldn't hurt). But without the posts variable, you could use some
prefix for titles and then filter them out by that prefix. Something
like:
{% for text, link, count in items %}
{% if text.startswith("DIRECTORY-TITLE:") %}
{% set title = text.split("DIRECTORY-TITLE:")[1] %}
{% endif %}
{% endfor %}
And then do the same check for display (but negated). I'm not sure if
this is fully doable from within Jinja2 templates; you might need to
expose some small helper functions in GLOBAL_CONTEXT.
