More details revealed about Windows 10 for phones preview of Project Spartan browser

"You'll find that this build has our new design for our Windows phone version, with the address bar on top, and a small actions bar at the bottom (a bug in this build means that the actions menu is larger than its intended to be). We've heard your early feedback about the position of the address bar, and we are looking closely at the design. We encourage you to try out, see what you think, and continue to share your feedback with us."
