Per a user request, I should implement a glow effect that mimics the Blizzard effect for buttons you should press.

A user requested to have a finish effect that shown the icon of the button in question on the center of the scree.
Don't know how the effects are implemented, but may be a future idea.

This is all the code necessary for registering a new effect:

OmniCC:RegisterEffect{
    id = 'id', --unique identifier for the effect
    name = 'string', --display name for the effect in the options dropdown
    Run = function(self, cooldown, duration)
        --whatever code should be run when the effect is triggered
    end
}

Implemented
