Having the flexibility to have the formula bar in the new modeling experience expended at the top versus jump to the bottom. In addition having the ability to move the formula bar around similarly to undocking and redocking so that the window has an auto-sizing feature when you toss it to the edges of your screen or portions of the interface (specifically the main viewing space).
