Media Library Categories (by Jonathan Christopher) registers the media_category taxonomy and attaches its terms to attachments through the standard wp_term_relationships table. The default media library shows a category dropdown filter and grid view, which works for navigation but does not surface size or MIME type as sortable columns alongside category.

SleekView reads the media_category taxonomy joined to wp_posts attachments and the standard attachment postmeta. Category, MIME type, file size, dimensions, uploader, and parent post become first-class columns. Saved views like "heavy attachments by category", "uncategorised assets older than 30 days", or "PDFs by contributor" replace per-category clicks with one screen.

Inline category edits route through standard WordPress term assignment (wp_set_object_terms) so the plugin's hooks fire normally and any listeners (cloud sync, audit logs) keep working. Bulk-reassign uses the same path, with conflict detection for direct writes.

Media Library Categories scales technically because it uses standard WordPress taxonomy infrastructure, which keeps writes safe and queries familiar. The default admin does not scale operationally because the category dropdown filter is the only way to narrow the library, and questions like "which campaign assets are over 5MB" or "which PDFs are still uncategorised" require either a grid scroll or code. Marketing wants per-campaign audits, ops wants storage triage, and editorial wants contributor reports.

None of those views exist in the stock UI. SleekView changes that by joining the taxonomy to attachments and postmeta and exposing every field as a sortable, filterable column. Inline term assignment uses the standard API so plugin hooks fire normally.

The result is a single auditable screen for the categorised-media work the stock dropdown made tedious.
