Polypane 9 introduces a fully rewritten screenshot feature with an integrated editor (powered by Pintura) for annotating, redacting, and cropping screenshots. The Elements panel gains autosuggestions for CSS, HTML, and ARIA attributes with live previews, plus improved tree view with flex/grid badges. The Meta panel now visualizes structured data (JSON-LD, Microdata, RDF) and includes a mobile-friendliness checker aligned with Google/Bing guidelines. New debug tools include a Target Size analyzer for tap targets and a Track Focus tool for keyboard navigation auditing. In-page zoom and search are now supported, the Outline panel received multiple improvements for links, images, and focus order, and performance was improved for sites with many CSS Custom Properties. The browser engine is updated to Chromium 102, enabling container queries and :has() by default.
