Polypane 17 is released with several new features and improvements. The meta panel now shows an overview of missing OG/Twitter/general tags, adds viewport and canonical URL warnings with copy buttons, and updates the max suggested title length to 60 characters. A new split slider in the reference image tool makes it easier to compare designs against live pages. The address bar now displays page titles and favicons in history and suggestions, with multi-word search support. Right-clicking images now offers more copy options including alt text, IMG tag, CSS background-image, and Markdown formats. The Track Focus debug tool now shows accessible role and name. The elements panel gains scoping root/limit badges, an improved class editor, and several bug fixes. The browser now supports a minimum width of 500px, uses native window controls on Windows, and runs on Chromium 120 which brings relative color syntax, :user-valid/:user-invalid pseudo selectors, and more.
