Future Updates

Currently, the plan is to continue developing a variety of multi-user functionalities. Additions such as a group chat/log, as well as allowing users to choose a personal chip color are coming. Ideally, a complete multiplayer update would also include methods to have active players democratically vote on ending a round of betting and spinning the roulette wheel.
