Easy Table of Contents stores its global configuration in the ez-toc-settings option: enabled post types, heading thresholds, which heading levels show, position above or below the first heading. Per-post overrides land in postmeta keys like _ez-toc-disabled, _ez-toc-alttext and _ez-toc-heading-levels. The plugin renders a TOC into matching posts on the front end, but the configuration spans one option row and many postmeta keys with no aggregate view.

SleekView Charts reads the same options row and per-post overrides, plus a parsed heading index of every published post. A Number card counts posts where a TOC will actually render given the current threshold. A Pie splits posts across rendered, below threshold, disabled by per-post override and suppressed by post-type opt-out. A Bar groups posts by post_type to expose template-level coverage. An Area trends post_modified on TOC-bearing posts to show whether long-form content is being maintained.

Because the data sits in standard WordPress storage, no separate sync runs. Filters span the audit table and the chart cards on the same dataset, and saved views gate by WordPress capability so each team sees its own slice.

Easy Table of Contents is the path of least resistance for adding navigation to long-form posts, with over half a million active installs, which is exactly the scale where coverage becomes invisible without help. The settings screen handles one global rule and many per-post toggles, and the front end either renders a TOC or quietly does not, with nothing in between for the editorial lead to look at. SleekView Charts turns the same options row, the same _ez-toc-* overrides and the same heading structure into a real dashboard: a KPI for posts actually rendering a TOC, a pie for eligibility status, a bar for post-type coverage, an Area trend for maintenance.

Same plugin, same rendering pipeline, but an audit surface that a quarterly content review can land on without opening every post by hand.
