Ability to save to Sharepoint, Creative Cloud and other cloud places like you can save to Document Cloud
A great feature would be the ability to talk to other cloud storage areas as well as Document Cloud.
The reason other places would be good is that you can manage the documents through Mac or Windows rather than having to open a browser and interact that way.
I saved to Document Cloud the other day thinking it would be useful but couldn't do anything with the files other than download them via the browser. A slow multi step process when all my other files are stored in other more effective cloud locations.
