In this day and age - many of us carry laptops. Some of us are "lucky enough" to have a monitor to plug out laptops into - thus giving us a "dual monitor" configuration. But, what happens when the "extra monitor" we have is on the left of the laptop/primary monitor? How many of us have "settled" for sliding off the right hand side of the screen to get to the "left monitor"? There is a very easy solution to this (at least in Windows).
