Ultimate Addons for Gutenberg (UAG) was the original product name for what is now Spectra. The plugin kept the uagb/* block namespace through the rename so legacy posts keep rendering, but sites running the old branding still face audit questions: which pages use UAG blocks, which posts use deprecated block names, and which reusable blocks reference UAG markup. The default WordPress admin lists posts and pages with no awareness of UAG block usage.

SleekView reads post_content across pages, posts, and any public CPTs, indexes uagb/* block usage per post, and surfaces it as a filterable column. Filter to posts using deprecated UAG blocks for cleanup. Filter to posts using forms or post-grid blocks for coverage audits. Sort by last edited to find recently touched pages that still use legacy UAG markup.

Inline edits to status, slug, and author write through standard WordPress update calls. The block markup in post_content stays editable in the block editor. The grid handles the audit; migration plans use the grid output as their input.

Ultimate Addons for Gutenberg was one of the earliest Gutenberg-native block libraries, which is why many long-running WordPress sites still carry years of UAG block usage in their content. The plugin's rename to Spectra kept the uagb/* block namespace for backward compatibility, but operational audits don't stop at the namespace level. Sites running UAG face questions the default admin can't answer: which pages use which UAG block, which posts use deprecated block names, which reusable blocks reference UAG markup, and which legacy forms still collect submissions.

None of that surfaces in the WordPress posts list or in the UAG plugin's own admin screens. A queryable block usage index changes the migration audit fundamentally. Filter to deprecated blocks and assign cleanup.

Filter to forms coverage to plan form migration. Surface reusables with zero references and prune them. Agencies handling older UAG client sites use this as a migration deliverable; in-house teams use it as the planning document for the UAG-to-Spectra branding upgrade they've been postponing.
