There is no doubt that much of the beauty of Mac OS X lies in its simplicity: to install an app just drag it into a folder, move it to trash to uninstall it ,keep it in dock to quickly launch it.
Three simple processes that Windows users are still dreaming of.
But what happens when you have several applications on your Mac but do not want to keep all in the dock?
You need a “launcher”, a small app that could be easily and that can afford to run any application in less than 2 seconds.
We therefore talk about QuickSilver.
