iPhone: Google has updated the Chrome browser for iOS with a new download feature. It also gets better support for the iPhone 6/6+.
Now, when you run into a downloadable file while browsing, you can download it, then send it over to any supported application. This means you can download something on your phone and send it over to Dropbox or Google Drive. It's a little feature, but it's actually incredibly useful.
