The Advanced Autosaver is an agent for saving your game after certain events. Once installed, a small hardrive icon appears on the screen, which can be moved to a location of your choice. Clicking on the icon will change it from green to red and back. When red, Autosave is off, and when green it is active. While active, Autosave will save the game after every birth, death or warp event.
