I have other suggestion. While stop? Let's delete ALL borders and colors, just white list and 2-pt light-gray color text. It's so cool, designers like this IPhone-style.
For serious, where are people with low vision eyes. And on 22+ monitors gray text has low contrast on white page. I see this on many sites. And wait while IPhone will change design and sites too ))
Another vote to allow hiding/removing items from the toolbar. There are buttons in there that don't need to be always visible (like share, screenshot, favorites, etc...) all other browsers allow for this and it's making me wanna switch
