Currently 955 touchscreen only supports 5 motions, i.e. 4 drag motions for up/down/right/left pan/roll respectively, and one tap motion for selection or entering functions.
It is very weir feel that every time when trying to go back to previous screen, we have to press physical 'Back' button instead of 'touching'.
I suggest Garmin to add one more motion, such as tap/drag combination from certain angle(like some cellphone) to duplicate 'back' button function.
How do you think?
