Love the ability to upload pictures in XC. Would REALLY like it if it could easily upload a drawing on tablet or smartphone. You can write on paper and take a picture, or you can write in an app and save the picture and upload that, but that is a lot of steps. Would be great if a drawing pad came up, or maybe copy and paste or send to from another app like Penultimate, Notability, Note Anytime or something. I would use this a lot in math and science where submissions are not typed.
