Google is rolling out a new feature to Chrome on Android called Minimized Custom Tabs, which, as of now, only works on certain first-party apps. Upon opening a link, you’ll find a downward-facing arrow in the top bar next to the close button, and tapping it shrinks the web page into a “floating picture-in-picture window” in the lower right corner of your screen.
Tapping the window expands it to full screen, returning you to the source website. Better yet, you can drag it almost anywhere on the screen, and if you want to close it, you can pull it towards the bottom.
