The Dock, Launchpad, and Mission Control
OS X has two features that help you keep open files and apps organized: Mission Control and desktop spaces. Mission Control allows you to see everything you currently have open so you can easily access the files or apps that you need. Desktop spaces are virtual desktops you can use to organize your open files and apps. Instead of keeping everything open on the same desktop, you can move some of your work to another desktop space to get it out of the way.
