usability enhancements
Preme for Windows 7 add several usability enhancements to Windows 7 that can make managing windows a little easier. You can bring up the Windows Task Switcher (or Aero Flip 3D) by touching the upper left corner of your desktop, slide windows in/out from the edge of your screen, keep a window on top by briefly holding it with your mouse, minimize a window with your scroll wheel, press ESC twice to close the active window and automatically expand the Start Menu by touching the lower left corner of your screen. The configuration dialog allows you to choose which of these features you would like to enable.
