You may not realize it, but the Options Bar, which seems permanently docked to the top of your work area, can actually be redocked to the bottom of your screen, or you can make it into a floating palette. To make it float, just click on the little tab on the far left side of the bar, drag it away, and voilà, it floats. To dock it at the bottom of your screen, drag the tab down to the bottom left-hand side of your screen and it snaps into place. You can even hide the Options Bar altogether by choosing Options from the Window menu. You can always get it back by double-clicking on any tool.
