Hm

It doesn’t do much that WP’s built-in functionality doesn’t do. It does enable to insert a long list of links at once via the menu shortcode, but it was just that menu’s links formatted as a list except filling out the entire post width (no space)… which did not look pretty at all.

The lists of posts and pages lists (an option available in WP already via “Link”) were short and did not allow me to pick any posts and pages not in the short list.
