Use up the whole window for the display game and then enlarge the chat window below.
Hm. Dont know. But, If you got PC, use of google chrome browser let you enlarge the tables as big you want already.
You can do this now by grabbing the corner of the game window and sizing it to be as big as you like. Here is a photo of a full size game window on my 27" display.
I understand how that works. Thank you. Great site by the way.
