WP Asset CleanUp Pro extends the free unload behavior with defer, async, preload, and combine rules. All of it is stored in the same postmeta keys (_wpacu_*) and the wpacu_settings option. The Pro admin lets editors set per-page rules and developers manage global rules, but it does not provide a site-wide overview of how many rules of each type exist, which asset types they target, or how active the rule set is.

SleekView Charts reads the postmeta and wpacu_settings option as flat rows and renders the data as chart cards. A Number card counts total rules across all types. A Donut splits rules across unload, defer, async, preload, and combine. A Bar shows top source plugins ranked by total rules applied to their assets. An Area chart trends rule edits over time, useful for documenting a clean-up sprint.

WP Asset CleanUp Pro continues to control front-end asset loading through its own hooks. SleekView Charts is read-only against the rule store and uses the plugin's own functions for any inline action where useful. Saved chart views are scoped per role, useful for letting an editor audit per-page rules without seeing global preload configuration.

WP Asset CleanUp Pro adds defer, async, preload, and combine on top of unload, which is exactly what a serious performance practice needs. The trade-off is that every new rule is one more configuration decision, and the plugin's per-page checklist plus global rule editor are not designed to answer site-wide questions: how many rules exist, of which type, on which plugins, edited when. SleekView Charts reads the wpacu Pro postmeta and the wpacu_settings option, and renders that data as chart cards on a single dashboard.

The plugin keeps controlling what loads, defers, async-loads, and preloads; SleekView Charts gives the team a shared screen to audit the growing rule set, scoped per role, and embeddable on the frontend for stakeholders without admin access.
