Objectives definitely sound like a good plan. Since there is so much to do in the game, so many main and side characters to focus on and so many outside activities, it can often be difficult to balance them all. I often find myself realizing, "Hey, I haven't actually done anything with X in over 2 weeks" but then I'm already planning to do Y. Having something like this would make it easier to keep track of what would currently be the best choice.
