Great to see the forum back and upgraded!
For closest to iGesture Pad experience on Magic Trackpad, enable tap-to-click and 3-finger drag in the trackpad control panel.
Unchecking 4-finger Expose while scrolling is checked allows 4 finger vertical scroll.
Unchecking scrolling, zoom and rotate leaves 1 or 2 finger pointing, but have to give up scroll.
A terminal command can also move navigation swipes to 4 fingers if you prefer nav swipes to app-switcher/expose:
defaults write com.apple.systempreferences com.apple.preference.trackpad.3fdrag-4fNavigate -bool YES
For supreme comfort with gel palm rests, or stabler resting on leg or couch, try this terminal command:
sudo defaults write com.apple.MultitouchSupport ForceAutoOrientation YES
After a reconnect or restart, turning the trackpad around and touching 5 fingers will invert the coordinate system so it works slanted down. So long as 5 fingers touch after turning it will always match your hand placement.
A fun trick to impress your friends if nothing else!
