Google has released Chrome 31 beta for Android. It has a new “Add to homescreen” option that can be used to pin websites to the homescreen. Certain websites will open in a full-screen experience and appear as a separate app in the app switcher.
Google has also added the Chrome OS UI to the development channel of Chrome for Windows. When a user installs Chrome in Windows 8 and sets it as the default browser, a tile will be added to the Start screen that can be used to launch the Modern version of Chrome.
Clicking the tile will open the Chrome OS UI with apps displayed along the bottom. Separate Chrome windows can be opened and snapped side-by-side. Learn more on The Verge here and download the dev channel version of Chrome for Windows here.
