Attention Effect, under the Settings tab. See link to pic...
Ohhh, OK. That is version 2.0. I use version 1.90, the free one. While you can only have one dock with it, it is all I need, and it has the ability to turn off those effects completely too, and I hate version 2.0's interface.
Wonder why they got rid of the ability to do that in version 2.0?
