Oxygen Builder splits its content into two stores: pages with Oxygen layouts use the standard pages post type with builder data in the ct_builder_shortcodes meta key, while reusable templates live as the ct_template post type with their own applies-to rules. The two screens in the Oxygen admin show pages and templates separately, which makes total Oxygen inventory invisible. A real Oxygen build accumulates dozens of overlapping templates, archive layouts, single-post layouts, header layouts, footer layouts, plus the pages those templates apply to.

SleekView merges both stores into one focused view. The Type column distinguishes pages from templates, the Applies-to column shows where each template targets, and Last edited cuts across both so you can see the genuinely freshest and stalest layouts together. That cross-cutting sort is the one Oxygen's own admin cannot give you, because it splits the data across two screens.

The most valuable workflow is finding stale templates. Oxygen sites accumulate archive layouts for taxonomies that no longer exist, single-post layouts for post types nobody publishes anymore, and header variants that were tested once and never deleted. Filter by template type and last edited older than a year and the cleanup queue is unambiguous. Migration-prep teams tag the rows they intend to rebuild and export the inventory as their project plan, with applies-to rules included so they know which templates require condition reproduction on the new builder.

Oxygen Builder gives developers extraordinary control over WordPress markup, and the price for that control is operational complexity. The same site might have ten archive templates, six header variations, four footer variants, and a dozen single-post layouts, each with its own applies-to conditions. The Oxygen admin handles each kind of content reasonably well in isolation, but the entire inventory is split across two screens with no way to compare a stale page against a stale template, or to find every layout (page or template) that has not been touched in a year.

That is exactly the audit a site owner needs before commissioning a rebuild or moving to another builder. Without a cross-cutting view, the audit becomes spreadsheet-by-hand work, and on a busy agency-managed site that is a multi-day project that gets deferred indefinitely. SleekView merges the two stores into one inventory and exposes the Oxygen-specific applies-to data as a first-class column.

The cleanup, the migration prep, and the freelancer handoff all run from the same view, and the answer to where the team's time is going on Oxygen maintenance becomes a query result.
