Gestures - swipe, pinch/zoom, force touch
In order to full use this as a UX professional, I would have to have the ability to include gestures, most critically for handing a stakeholder a wireframe or design. Gestural swipes, two-finger zoom, force-touch, etc. Otherwise I don't think too many experience UX professionals will be able to properly communicate core functionality and the behavioral imperatives incumbent to the process.
I second this; the simplest apps require these as part of the navigational experience. I'd suggest starting with swipes/taps and moving up to force touch as the app develops.
In most of the UX softwares either there isn't building the design or creating user gestures. As there is design I think it is necessary to add user gestures like pinch, tap, click, swipe up, etc to create the interaction like ' on swipe up fade widget 1' etc. Cheers XD :)
Swiping and Multi-Touch is a must-have in mobile prototyping. Also the ability to read x,y-axis values while swiping and connect it to other object attributes (eg. Alpha)
