Here's a great little video tutorial from Shane Ross at Little Frog that will help you to take full advantage of FXBuilder in Final Cut Pro, a scripting and automation tool that allows you to create custom plugins. You won't be able to create any serious razzle-dazzley plugins, but if you want to share custom color correction settings, for example, FXBuilder lets you script settings and make an actual plugin file which can then be shared with other folks running Final Cut. If you are weary of coding, this might not be up your alley, but the scripting involved is far from heavy duty and can easily be tackled with the help from this excellent guide.
