Launchpad—my biggest wish for 10.10

Launchpad makes both the desktop metaphor as well as the dock seem redundant at best, and downright vestigial upon inspection. Springboard solved this problem for mobile devices, and Apple realized the same solution applies regardless of the computer's size when they implemented Launchpad into 10.7 so many years ago. With 10.10, I hope they'll finally allow us to disable both the dock and the desktop.
