Why You Need SizeUp for Window Management

Arranging windows on Mac OS X is tedious and imprecise. Even after dragging, pulling, and, re-dragging windows, you end up with inefficient use of your available screen real estate.

SizeUp will help you quickly resize and position your windows to make optimal use of your screen while saving you time and frustration.
