One of the biggest things I would love to see is the ability to make a node or a character sheet in the system. Having a place where you can have all of your skills for easy rolling would be nice. The Macros are nice, but having a lot of NPCs and not having the Skill roll macros you need can be a little tiresome having to write them out over and over again.
Also it will help the players having their sheet in the program than outside of it.
