Does anyone else think that the surface pro 3 pen could use a grip? I designed this guy and I'm toying with the idea of starting a kickstarter for it, but I want to get some feedback from other SP3 users. I find that the grip greatly improves the ergonomics of the pen as well as the utility of the two side buttons. Before I had to reposition the pen every time I wanted to use the side buttons, now my thumb is always in the right spot. Makes the writing experience that much smoother. Let me know what you think.
