Little known as a gesture program: Power-Pro with mousegesture and eventually mousetrap plugin. It has a powerful language that manages every detail of the system. In addition to managing the classic gesture, runs every mouse event, and manages all the gesture even before it was finished by the time the mouse is still "down". Unfortunately gesture are not every as responsive as a specialized program such as S+. It also not have a gui and the configuration is only via ini and script files.
