"Sometimes, you find an application that you really, really like, but
when you run it, the icon takes up valuable space in your Dock. With
Dock Dodger, you can rid almost any application of its Dock icon,
giving you your Dock back.
With Dock Doger, removing the Dock icon is as easy as
Drag and Drop. Simply drag in the application you want to Un-Dock and
Dock Dodger takes care of the rest. When you re-launch that
application, it will be sans Dock icon. Want the Dock icon back? Just
re-drag the application into Dock Dodger and everything's back to
normal."
