Add groups tabs, but not too much

[Khalif Foster]

So, when add group tabs, can group it, like 5 to 10, and so on, so it will add to browser, so it will not add alot, I add 70 tabs, so had to wait, so it freezes it up. So, need to highlight each tabs. So, it is not just group of tabs but highlight tabs that is important. And add the merge, so two same tabs will merge as one. Even two window, and two tabs, within one session. It can be either choice for window or/and tabs, or both at once within one session. Then result to add to window as a whole.
