I haven't had to integrate a character into a game yet, or as a GM integrate characters for others either. But one thing that I think would be kinda cool is something where I could upload my character sheet and consequently my character to my profile and then I can bounce that from game to game. It would save GM time I feel as they wouldn't have to connect the dots, it would be more of a plug and play set up. I have DMed in person before and I know that it would be crazy if I had to come up with minis, and input the character information for the other players around the table. Just a thought.
