> Being able to set audio keyframes from the audio mixer (tool-bench)....
You can. Go into User Preferences - Editing and turn on "Record Audio Keyframes".
> Wouldn't it be cool to scroll through your clips like you do album art in iTunes cover flow?
The non-list iTunes interfaces were really designed for non-professional users who love eye candy more than functionality...if going through clips in FCP looked like that, I'd look for another editing application!
