Custom Post Type UI is the most-installed way to register post types and taxonomies in WordPress, and the Extended add-on widens what each registration can do. The data still lives in wp_posts, wp_postmeta, and wp_terms + wp_term_taxonomy, just with the registration handled by CPT UI Extended. The default admin for any registered post type is WordPress's standard list table, which is fine for editing one post at a time but doesn't expose meta fields, custom taxonomies, or featured imagery as columns.

SleekView reads every CPT UI Extended post type as a first-class source. Meta keys become opt-in columns, taxonomies appear as filterable cells, and standard wp_posts columns (status, date, author) are available alongside them. Sorting and filtering work even on meta fields, which the default list table can't do without custom code in pre_get_posts and posts_clauses.

Inline edits route through the WordPress core update API (wp_update_post, update_post_meta, wp_set_object_terms), so any plugin or theme that hooks save_post or related actions continues to fire as expected. Saved views per role replace the practice of registering custom admin columns and sortable handlers per post type, which gives developers their afternoons back and editors a workable admin.

Custom Post Type UI is everywhere because registering post types from the admin is a sensible default for non-developers. CPT UI Extended adds the things teams need on top: extra status registration, more taxonomy options, and richer registrations. The piece that's never been first class is the admin column set.

The default WordPress list table shows title, author, and date. Anything beyond that means writing manage_*_columns filters, manage_*_sortable_columns filters, and matching pre_get_posts handlers per CPT. On a site with a dozen post types that's a real amount of code, and it's the kind of code that doesn't pay off intellectually.

SleekView replaces all of it. Any CPT becomes a sortable, filterable, inline-editable table by reading its registration. Meta fields are columns.

Taxonomies are filters. Statuses are options. Edits route through WordPress core so save_post hooks keep firing.

Developers stop hand-rolling list tables, editors get an admin that matches the model, and the registration stays in CPT UI Extended where it belongs.
