Bookmarklet - download all links on a page

download.js

javascript:(() => {
  const items = document.querySelectorAll('a');
  let delay = 0;
  for (let index = 0; index < items.length; index++) {
    const item = items[index];
    item.setAttribute('download', item.getAttribute('href'));
    setTimeout(() => item.click(), delay);
    delay += 500;
  }
})();

Omg, thank you so much! This is way better than complicated macros.
