i like it just as it is now, thanks for asking the players....i'm "old school"
Just thinking out loud, kissinger?
W.R.T. to the mock-ups: I think this collaboration is definately converging on the closest thing to a win-win situation - but of course not all will be pleased (you can never please everyone).
That praise being said, I agree with the move-mark on comments (auto-annotation-esque) and the default landing on the Move tab, with any new messages being indicated visually on the Message tab or non-intrusively elsewhere. Oh... and the "Draw offered" indicated on the move list is also a great idea.


Looks good.
I second TheGrobe's suggestion of being able to save annotations (notes) to the games as you're going along with move marcations - that would be amazing as I think I'd actually have a chance of learning from my mistakes that way.
