Few things missing that would be nifty features, parent-page relations (at least down to 3 levels), and widgets (basically mini-modules for putting things in different areas of the page).
For instance, you might have a 'recent posts' widget which you put on the left side of the page and a navigation widget which shows a different navigation on the top of the page and on the bottom of the page, etc...
