I would personally like to see a better piece count thing (the bit where the pieces are "kept" when they are taken off the board"). At the moment on live chess 2.0, the pawns overlap each other, then so do the knights, bishops and rooks (if you manage to take both of the pieces of the board). I prefered the old version (live chess 1) of this where the pieces just lined up by each other when they were taken off the board.
I agree completely.
I think he's talking about lag.
