One of my favorite features in Lion, as a laptop user, is its take on full-screen apps. This works especially well in apps like Mail & iCal, where the interface gracefully uses every pixel of the screen.
However, not every app utilizes full-screen fantastically. These apps pretty much just expand all their UI elements to fit the screen. Safari, while I enjoy using it full-screen, has too much travel when using the mouse to reach certain areas. Also, having the address and search bars separated is so 2008.
Henrik Eneroth took it upon himself to reimagine the full-screen browser into something more usable. It's ideas like this that should be coming out of Cupertino. His mockup is fantastic, and I think almost everything he touches on is spot on.
