Visio 2016 with Surface Pen
Touch functions of Visio 2016 are excellent, but i miss them working with a Surface Pen on Surface Pro.

Comment style annotations for things like modification suggestions would be great. Lot easier to communicate changes quickly when you can scribble over everything.
Being able to draw a rough link between entities such that the number of adjustments required would be great too.
Sure there are plenty of other areas that would also benefit, but for a lot of them to be useful the input recognition would need to be near perfect to be of any practical use (I'm sure having some way to provide context could help as it would cut down on the possible interpretations).
