• larger paper (3x3 screens)
• scrolling using either D-Pad, ABXY, or pen (hold L or R)
• dual screen support (overview on top, zoomed view on bottom)
• open shapes (drawn shapes are only closed if the end is close to the start)
• Using the actual shape for picking => o more accidental deletions
• updated to box2d 2.0 (svn r20)
• using ds hw div/sqrt in box2d
• if simulation is behind time, 2 steps are performed at once => subjectively faster
• faster and better drawing code
• pins are hidden during simulation
