Three great new tools

Task management: Toodledo,  Different than Remember The Milk, maybe better.  I’m trying it out and may switch permanently.

BetterTouchTool:  Lots of gestures for your Mac.
BetterSnapTool:  A subset of the gestures in BetterTouchTool, but in addition allows you to move a window by pressing a modifier key and moving the mouse.  If you use a touchpad, this is actually just a modifier key and dragging your finger.
All are free.
