WIP: PR merge checklist #2638

Events

Most of these are due to GitHub losing events on AJAX navigation

• Avoids JSX events like onClick (use delegate-it instead)
• Avoids element.addEventListener (use delegate-it instead)
• The first parameter of delegate is document/document.body, not anything inside the ajax container

Meta

• screenshot is not false unless really hard to show
• [](# feature-name) in readme is the right one, not the name of another copy-pasted feature
