The Go Launcher Dev team has just released the Go Note Widget, a homescreen widget that you can use to store Todo list and scribble stuff down (especially when you're bored in a meeting). You can also add schedules, set alarm notifications, change the skin of the note and also share them if you wish.
The Widget itself is FREE and requires the Go Launcher to be installed which is also available for FREE. So do check out this excellent Widget by the Go Launcher team and start doodling:
