To add to that 'sheet' idea, a section for OOC info wouldn't go amiss either.
One might argue someone could do all this in set info currently with enough jank, but the idea here is accessibility, ease of use and uniformity for something that could add an additional layer to how we approach each other and interact. There has been many an occasion on an MMO where thanks to tools with formats like this, it's enabled me a 'Roleplay hook' that's often helped me bridge a divide and break the ice with a talking point based on the 'current infomation' given to me.
When contending with a monster, you'd be wise to give the devil his due.
