CPT UI Extended is the premium tier that adds layout assignment, archive customisation and template controls on top of the registration capabilities CPTUI ships in core. Once a site has half a dozen layouts and a handful of templates running across multiple CPTs, the standard admin surface is a list of settings screens. Which posts use which template, which CPTs run the default layout, which archive pages have custom configuration: none of it surfaces in the WordPress list table.

SleekView reads the option storage CPT UI Extended writes and treats layout, template and archive assignment as queryable columns. The CPT's own list table gets a template column so editors can see and change assignments inline. A registry view shows every CPTUI-registered post type with its assigned layout, archive page and template counts. Filter to find the posts still on the default template, sort by last-modified to see which records were touched during a redesign.

Inline edits write through the same option storage CPT UI Extended itself maintains, so the plugin remains the source of truth. The same dataset can be flipped to a kanban view grouped by template assignment, which is useful during a layout migration.

CPTUI is intentionally narrow; CPT UI Extended widens it by adding layouts, templates and archive customisation on top of the registration step. The trade-off is that the configuration surface grows fast and the standard admin presents it as a series of independent settings screens. There is no built-in column for the assigned template per post, no built-in registry view of CPT layouts, no way to bulk-reassign during a redesign.

SleekView reads the options CPT UI Extended already writes, treats them as columns and pivots them into editable tables. The configuration becomes a queryable, editable surface rather than a forest of toggles. For a developer maintaining a CPT-heavy build, or for a design lead rolling out a new template family, that is the difference between feeling the change and executing it.
