Separate the Chat box and the box that tells you what is happening at the table (like what hand is being dealt, who won, and other information)
Basically this will help clarity. Often times chat messages that are submitted mid-hand are overrun with the other information such as who won the hand and other information.
If these were separated into two different boxes (one on the bottom right and the other on the bottom left) and all the table actions (fold, call, check, and raise) were placed in the middle, then i believe the website would not only have a better look, but it would also be more versatile and efficient
