At the moment the touch gestures work for navigation (pan/zoom) but fail horribly for Undo. I always use 2 fingures when trying to navigate but in some instances Photoshop thinks I used 3 fingers and activates Scroll Undo. If this happens then it Undo's your work bact to the dark ages and if you work as fast as I do and you accidently click with a pen - that accidental undo is permanent!!!
Please make Touch Gesture for UNDO is own preference option so I can disble it.
