A while back, we’ve covered about Chrome 32 Beta update which lets your track down noisy tabs with the help of indicators and we also mentioned in that post Chrome on Windows 8 mode looks completely different to the current stable version.
See what Google done, it has added a shelf at the bottom (similar to taskbar on Windows) by placing icons of Chrome, Gmail, Google Search, Docs, and YouTube apps and app launcher. The shelf position can be moved and set to either left or right like taskbar on Windows 7, and you can autohide that shelf as well right-click on app launcher icon to get these options.
Chrome window in Metro mode can be moved to left or right side of screen and minimized, so that you can see other opened Chrome windows easily. Hover your mouse pointer over maximize button at right corner of window to see these.
