I added two new categories to the blog: Life, for talking about me (myself and I), and Money, for discussing monetary matters.
At the beginning of the blogging, I decided not to have too many categories, as I try to keep myself focused. Somehow the focus has drifter (or searched for its place) and I recently found out that half of my posts are in the default Nomadig category.
I’ve now sorted things out and went through all my posts and reassigned the categories.
During this process, I found out that WP generated different category lists with
wp_list_cats(). Only the latter supports hierarchies. Hopefully those people at wordpress.org don’t fix
wp_list_cats() as it’s perfect for my needs.
