Switcher is free utility for Windows Vista (running Aero) that lets
you arrange the windows on your screen in different ways. The
default view is the "tile view," which arranges the windows so that
you can see all of them, even across multiple monitors. Another
view, called the "dock view" magnifies one window and arranges the
rest along the side. There is also a grid view, which is a good one
to use if you are also going to use the number shortcuts for the
windows (the first 9 windows can be activated by pressing the
respective number on the keyboard).
Your desktop can be treated as a window, too. In this new version of
Switcher, the windows now have a customizable background color,
border, and a label which can display any of the following: the
filename of the application, window icon, the number shortcut, the
memory used in megabytes, the process name and the window title.
Other new features include filters to help you narrow down the
windows that appear, the ability to close windows during a session,
smoother animations, and additional keyboard shortcuts. To learn
