First up, FATE is awesome. Second, I agree with Lena that it is important that players be able to add, remove and change these as needed to reflect their current state.
Honestly, I find that things like this are the most important part of the @history. Motivations. Ticks. Personality quirks. Vices. Hates. Draws. I always put these things into a new PCs history and I keep that list updated off moo.
I was going to suggest that the history should have these things and can be updated but then I realized that histories (mine at least ) can be as bad as half a year's notes. A distinct place to keep these things that GMs can easily access would be pretty cool.
On the flip side, staff would need to understand and respect that these might not always be completely up to date. And that, like most things, different people can interpret the same words in different ways. It's not a commitment by the player to always make their PC act in accordance to staff's interpretation.
I'd hate to give staff the wrong idea and, while I would never do it on purpose, it could happen without me intending to if people run with their own interpretation of the words.
