- Erases the black border, makes all the windows movable, and allows shift-click & CTRL-click to add/remove 10 or 50 components at a time on the design screen.

- Good for multiplayer simultaneous games over a LAN, option to blink the keyboard lights to show who is done.

- Simulates a ship taking damage, useful for observing the fancy effects that leaky shields and armor have. Good for improving your designs in a mod with such features.
