I just got my Hero a few days ago, previously I had an Instinct. So far I love the Hero, but one of my few complaints about it is having to take pictures by pressing the trackball. The trackball just feels odd to press and most of the time I have to press it multiple times for it to take a photo. Anyone have any solutions to this? I doubt there is a way to change this in the settings, but is there an app or something that uses a more convenient button for photos?
