Has anyone had the opportunity to try the Moxie Track (green die) system presented in Transhuman?

If so, what are your thoughts on it? I find myself having difficulty keeping track of everyone's motivations so having a chance for players to add "I am going to roll X-skill, for y-reason. Also this relates to my +/-Motivation." With me just needing to say "yes" or "no" along with the "Okay, roll with a bonus/penalty (situational)." It all seems like a decent idea but figured I would query the forums.
