Those of you who have a MagicMouse, you know some of the limitations. MagicPrefs is a free menubar and preference pane application for OSX that eliminates many of those limits. It adds functions like Middle Click , Hold Down Both Mouse Buttons , Spaces , Expose, Dashboard etc.
Also featured is a real-time display of the fingers touching the surface of the mouse that you can enable to test and monitor the way the mouse sees your input.
MagicPrefs is a application meant to run in the background all the time hence it has no interface elements to get in the way and it uses less than 1% CPU and is optimized for a minimal impact on the system performance.
The site does offer this advice:
Take it easy with the gestures, take your time to get comfortable with each new gesture before adding another.
