Capture

This is the best iPhone/iPod Touch screenshot utility yet! Like the utility Screenshot it adds a button to snap a photo that hovers above what ever application you are in, it also has a button to exit, that closes the hovering snap button. The huge bonus with Capture is that the buttons are movable! Simply touch and drag the left side of the bar and you can position it where ever you want. This makes it very easy to navigate around applications without the buttons getting in the way. The other awesome feature is that the photos are automatically added to your camera roll and are viewable with the Photos application.
