Polypane 6.3 introduces several new features for web developers: a tunnel vision simulator that lets developers experience sites as users with tunnel vision would, a target size cursor debug tool showing a 44x44px square to verify clickable element sizing, and web manifest support in the Meta panel. The reload button has been relocated to match Chrome's layout. The Outline panel now warns about non-descriptive link text, redundant image alt text, and shows autofocus elements. Additional improvements include updated Discord/Slack social previews, better scroll syncing when the body element is the scroll container, and performance gains in the elements panel. Patch releases 6.3.1 and 6.3.2 add custom live reload ignore patterns, custom font size in Live CSS, updated Twitter/Google previews, and various bug fixes.
