Hi,
a neat feature that I miss from Chromium based browsers is the ability to cycle through the address bar suggestions when reaching either end (top or bottom) of the suggestions list. On WebKit-based browsers (Orion and Safari) when you reach the end of the suggestions list, you can't "keep going" further down to get back to the top one while on Chromium browsers you can. An example of where this would be useful is if you instantly see that the bottom-most suggestion is the one you want so you could just press the up arrow once to immediately arrive at that specific one instead of having to "scroll" all the way through the ones ranked further up in the list.
