Autoptimize works by collapsing dozens of CSS and JS files into a small handful of aggregated bundles and serving them directly from disk. The optimization is real, but it is also opaque. The default admin reports total file count and cache size; it does not list the files, so cache bloat sneaks up on hosting accounts that bill on disk usage.

SleekView Charts indexes the autoptimize cache directory and reads the autoptimize_* options, then renders dashboard cards over the same data. A Number card holds the total cache size, a Donut splits files by type, a Bar ranks exclusion patterns by match count, and an Area chart traces cache file ages so old aggregations sort to the top of the cleanup list.

The dashboard is read-only against the cache directory and routes inline cleanup actions through Autoptimize's own functions. Aggregation, exclusion lists, and image optimization stay in the plugin's hands; charts just provide the audit surface that the default admin never built.

Autoptimize collapses many small files into a few large ones, and that change is worth keeping. The opacity is the cost. Cache bloat, dead exclusion rules, and forgotten image quota usage all hide behind aggregate totals that look fine until they do not.

The same data Autoptimize already writes to disk and to wp_options is enough to answer every interesting question, once it is rendered as a chart. The plugin keeps doing the heavy lifting; the dashboard just gives the people responsible for performance a number to point at.
