There are some improvements I can think:
-better interface so the chat when you watch a game doesn’t hide the game.
-a button, when you are watching a game, to “jump” 5 moves ahead.
-an easy access to the finger of the players (specially when you are watching a game)

Those are great suggestions.

Another couple of wish-list items:
* When flipping the board while watching a game, there seem to be four different options; I just want a simple way to flip between white or black at the bottom, and don’t want an “auto” mode or a “crazy upside down mode”. Please simplify this.
* Please add a way to show the move list while you’re playing or observing a game.
* Please add an icon that shows what each of my friends is doing (watching/playing/analyzing)

Also, please see my post in the ICC for Windows forum; there’s a bug in Android that seems to unsubscribe me from non-default channels when I quit the app.

Thanks!
