SwitchUp is a unique application that allows you to manage multiple profiles of settings (preferences and data) for almost any application. It's like a multi-user environment for each application.

Do you ever get an application set up just the way you like it, then need to create another profile with different settings? Maybe you just want to test something out, or your friend wants to try that shiny new app you got, or maybe you use the same Mac for both work and home. That's what SwitchUp is for.
