Would be nice. It was there in previous versions. Would eliminate extra mouse clicks. (Because I'm nothing if I'm not lazy.)
If you go to Manage Pages for whatever reason, then decide you want to create a new Page, you have to click on the Write tab, which defaults to New Post. You then have to click on the Page tab.
This way, you're already at Manage Pages. Just click a link that says Add [Create?] Page .. one click.
