DraStic

I hate taking built screenshot with holding. down volume (-) + power button but sometimes will damaging my button that I press or sometimes the screenshot doesn't save (Still "Saving Screenshot" in notification). I need built-in screenshot on DraStic like DeSmuME and the other emulator.

Same problem

I am feeling lucky samsung uses palm across the screen for screenshots on my device.

But it would be a nice option, not sure if apps get access to the actual screenshot function or if some in emulator version would need to be made though.
