That's correct. You cannot automate Windows Phone application with this tool, sorry. Our goal was to automate web interface. You can simply navigate to any page, and automate typing, clicking, etc. By no support for touching we understand no possibility to generate touching events (swiping, pinch for zoom, etc.). You can simulate more generic ones like clicking though . Lack of this feature is caused pretty closed sandbox in which applications are running, since this driver is just regular windows phone app (no hacks included) I cannot do anything more than other apps.
Thank you for kind words.
