Please restore the tab grouper included in the original Brave. When opening a lot of tabs, Brave would nicely kick some tabs to another group(s) that you could slide over to using a slider that would appear below your tabs.
This was very nice for people who have a gazillion tabs open at any given time for research, bookmarking, business, you name it. Not all tabs are bookmark-worthy either. Some want them open as a reminder to do something.
