The Surface Pro 3's pen is arguably a defining feature, but you haven't had official control over it so far. As of now, though, you finally get some say over the stylus' behavior. Microsoft has posted a Surface Hub app that lets you customize both the pen's pressure sensitivity and its top button. Right now, the software isn't likely to please demanding artists and note-takers -- you don't have fine-grained sensitivity tuning, you can't launch any app you like and the side buttons are strictly off-limits. The crew in Redmond is willing to add features based on feedback, so don't be afraid to pipe up if you have dreams of launching Photoshop with a single thumb press.
