UI for editing homepage — the jiggling icons on represent.. what, exactly? Does this really feel natural to anyone? Is the idea that they needed to have some way to represent “edit mode” without occupying screen real estate?
Moving the “+” button on Safari down to the bottom toolbar is a nice touch — it lets you add bookmarks without scrolling to the top of the page. It would have been even nicer if they allowed you to access the URL bar without scrolling. (I sometimes find myself on webpages with hundreds of comments on them. Scrolling up to the top to access the URL bar is AWWWFFFUUUULLLL!)
The new location feature for maps is awesome.
