I suspect that a more confortable play when at table would help to have more interested players. - faster bets : a cursor permitting to choose the bet size very quicky - less time for players (that have no problems of connection) who might make use of a time button (such a button would allow, for instance, 1 minute of additionnal time each hour). - possibilty of hiding/showing our cards when losing a pot - possibility to write personal notes on players - access to statistics on our past hands.
