I’ve got a couple of things which would be good to have in the OP:
Order by title (i.e. alphabetically)
We can now also order by title (which is super useful):
Subcategories
You can target subcategories using this format:
category:catslug:subcatslug
Feature request - a banner or similar
While it is absolutely brilliant to have these filtered views, it would be super helpful to have an explainer up the top of it (analagous to the Category description) so users understood what it was about.
Alternatively, it would be even better if we could specify one of these filters to be the default view of a category (or even a tag).
