Page Blocks Builder 3.1.0 Adds Performance Analysis
I've released GT Page Blocks Builder 3.1.0 with a Performance view in the full-page builder and an Analyze section control in the Block Editor inspector. You can check section size, repeated CSS and image, script or font hints before publishing a page.
Section CSS is also processed less often. In a local 100-section fixture, parsing dropped from 101 passes to 1. That's a processing check, not a promise about your site's PageSpeed score. Per-section CSS deferral is available when you choose it; keep hero and shared layout styles inline or loaded normally.

Existing pages keep their content and loading choices. See the 3.1.0 release notes before turning on deferral, and tell me if the Performance view flags a section you can't explain.
