PluginPal for Mac

From BKMS:

iMovie users typically accumulate an abundance of effects--some used on every project, others only occasionally. When your screen is cluttered with a list of every available effect, finding the one you actually want can be an annoying waste of time. With PluginPal, you can create customized plug-in settings for specific projects, and then move easily from one setting to another.
PluginPal gives you a list of your installed titles, transitions, and effects, and lets you turn them on and off. You can save a setting of specific plug-ins that you?ve selected, and recall settings from a popup menu. You can override a setting, save a setting under a new name, or delete settings you no longer use.
PluginPal will even enable and disable the effects, transitions, and titles that shipped with iMovie. Screen space is precious, and so is your time.
