Hello all,
Please remove or comment out this button as I destroyed my drone unaware of it. Besides reading the code an "!" is not warning enough that it cuts the power of the drone. Please either give a small warning when a user presses this button with a cancellation timer before it activates or disable it completely. Please consider that the released GroundSDK as distributed by Parrot should be conservative on their demos.
