Google recently implemented Tab Groups in the Chrome browser. Tab Grouping has been in development for quite a while and Google says the feature is now ready for the users. You can use it to lump similar websites under one umbrella, which is called a group. These groups are organized by their name, color, and tab strip. To create a new tab group, right-click on a tab and click Add to existing group and then select ‘work’ Tab Groups can be accessed from the tab context menu.
