Tab Group separator

if I click using the wheel  or choosing "Open in new tab" Internet Explorer and previous preview of the new Edge automatically create a new group of tabs I find very convenient and I hope you will bring back this behavior.

Another question is that in the new implementation when a tab in a group is selected the line indicating that it belong to a group is gone, this make less clear that the tab is part of the group, especially for the last tab in the group. IMHO the implementation in IE still better.

And finally we need more options for groups like, now we can only add a tab to a group or remove a tab from a group, will be usefull if we can:

1) close all the tab in the selected group (as already available in IE);

2) close the others tab and leave only the tabs in selected group open (as already available in IE);

3) add the group to favorites;

4) add the group to a collection;

5) refresh all tab in the group;

6) Open a favorite folder as a group;

7) Open a collection as a group
