Starting in Chrome 69, the browser features significant changes to the user interface. These include a 'Material Design Refresh' theme with rounded tabs, the removal of the 'Secure' text badge for HTTPS web sites replaced by a Lock icon, and a reworked new tab page. Also, the browser allows changing the position of the New Tab button (+). Using a special hidden option, you can control whether it appears to the left of tabs or to their right. By default, it appears after the last open tab.
