I definitely need a rules page. But I think more than that I need to more clearly communicate during gameplay where people are in the hand. So for example, if you're playing with 2 pawn rounds and then 2 piece rounds (and, say, with "bet after each piece" turned on) there should be some visual representation of where the player is in that sequence at any given moment.

Or if you have the "bet every 11 moves" setting turned on, there should be a countdown while playing in the chess phase how many more moves until the next betting round.
