Thanks for your response! I can definitely imagine many scenarios where it’s helpful to further filter the output of the category filter — especially in large directories.

For directories, 2 filters are needed too. One for cities, other for type of business as example, if not, all tags in the list are mixed. Or if we want to go granular, it could be category and subcategory like restaurant > Thai restaurant. 2 Filters at least, is a must for sure :)
