Add option to open saved group in current window

[Al12rs]

From what I could see find users are only able to open a saved set of tabs in a new window, while I would like to be able to work with only a single window open.

What I would find very useful would be to have a button to open the tab group in the current window, and possibly close all tabs of the group in the current window.

This is a bit of a change from the workflow proposed by tabli, which proposes the use of windows to organize tab groups. This feature request would instead propose to detach the tab grop abstraction from the window container and make it an indipendent concept.

The end goal would be to allow users to save only some of the opened tabs in the current window, close a grop of tabs, reopen a grop of tabs without having to open multiple windows of Chrome. Saving only some tabs is more or less possible by saving the current tabs and then deselecting the ones you didn't want so mostly it would be to allow opeing a group of tabs in the current window and close it.
