The Note 5 is a big device and it can get pretty tiring to hold it up for long periods of time. I have actually had digits fall asleep holding the Note 5 watching a football game on the watch ESPN app. Samsung may have a pretty cool trick up their sleeve for the Note 6.
Samsung filed a patent for an S-Pen that folds into a kickstand way back in the third quarter of 2015. The patent shows an S-Pen that would stick halfway in the device and halfway out. It bends in the middle making the kickstand. As long as the mechanism that allows the S-Pen to fold in half is nice and firm when in straight S-Pen form this might be cool. If the hinge is not sturdy and it folds in on itself randomly this could be pretty awful. Of course this is just a patent and who knows this could be vapor ware.
