Sophisticated web apps can make videos and other files available offline, but finding that media is tricky if the website doesn't give you an easy way to find it. Soon, though, that search might be trivial. Google has released a Chrome 80 beta whose centerpiece is a Content Indexing framework that lets progressive web apps list all their offline-capable content. You could find a must-have photo or report without wading through pages to get it. The framework is just in an an "origin trial" phase between now and Chrome 82, but relief is in sight.
