Every time I need to admin other people's WordPress sites, I get the feeling WP is actually a trap. Things are working so badly. For example I search for how to have a page without theme/theming. Apparently, not possible. You basically only find bad advice online, mostly script kiddies level unmaintainable stuff.
I see someone mentioning "Page Theme" (https://wordpress.org/plugins/page-theme/), a plugin. So I go to plugin search to find exactly that plugin. Search shows me 278 results, first page no luck.
