I do dislike what they did with the recently closed list. I tended to use that why too much.
I have one on the lower right, comes in handy.
I know exactly where it moved. But it used to be right below the pages and have the last few as individual links. So if I closed something by mistake it was a simple ctrl-t and click. Now it is ctrl-t, go to the corner, click, click. Not as useful.
