I know they wont, but it would be so amazing if they added gyro aiming.
I hope that they somehow incorporate the printing mechanic to export to the gallery, much like how they did it with this game on the Wii VC.
I mean with the screenshot button, I'm not sure an additional feature is needed, if you really like an image and physically want a copy of it, you screenshot it, then share it to your facebook or twitter or whatever through the Switch, and then print a copy off directly from your printer by grabbing your image on your PC from wherever you shared it.
It was a fun novelty in the past to find ways to get the images in our video games into our hands physically, but now we can all easily do it with any game on modern hardware if we want to. It makes the whole experience a bit less magical though, I will agree to that. Gone now is any kind of need for something unique like the Game Boy Printer or a kiosk at Blockbuster, and that's kinda sad. I suppose it's just nostalgia talking, but I really loved stuff like that.
