For those of you who used the Cyanogen 7 ROM, one of the features is a series of toggles that you can slide down from the notification bar that has 7 different things you can toggle, much like the PowerToys widget, but accessible at ANY time. It's very useful. Unfortunately, it's unique to CM7 as it's a part of the notification dropdown.
Now, Notification Toggle promise to bring that to a regular phone.
Unfortunately, it doesn't work on my Droid Bionic, and the author wrote that very few phones can support direct toggle out of the box. Instead, a pop-up box is presented to do the toggle.
Still, it's free, so don't complain too much.
