The options to create a new tab, close every tab except the current one, bookmark all open tabs and reopen a closed tab are all destined for the chop, after developers concluded they weren't used often enough to justify their existence.
Seems like I'm one of the minority as I use new tab and reopen a closed tab multiple times a day. Chrome becomes less and less relevant by the day.
