An extension helps you manage tab groups better The newly added tab grouping function in chrome is very helpful. however, one of the things it does not allow the user to do is to pre-define rules for tab groups. with this extension user able to config the tab's group based on the tab's URL or regex rules. when a new tab is created it will be added to the corresponding group based on the rules user-defined. An auto group flag in a pop-up view is used to suggest if the extension will auto move the tab when it is created or updated. if this flag is off then the user will group the tab by clicking the “Group all tabs” button.
