Over time, with more applications being installed on my computer, my applications Grid became larger and larger. Instead of seeing a small bunch of icons that I could easily recognize and navigate, I literally had dozens of icons on my applications Grid. This made it very difficult to distinguish the one application that I was looking for. It was like looking at a sea of multi-colored icons that were all blurring into one. Maybe you know what I'm talking about?
Naturally, I had my most used applications accessible directly from the Dock, but for all of my other applications, I started using the Finder or Spotlight to locate and launch them instead. That is, until a friend showed me an obvious way to navigate a Grid and launch an application very quickly.
