Im not really worryed about the playmat. But in certain games like LOTR, and l5r alot of cards can be on the table at one time. Is there a way to resize the cards. used to be able to do it with my scroll wheel but now i cant..?
Press the arrow button in the top-left corner of the playmat (adjacent to the card preview) to reveal the table controls. Use Scale or Zoom to alter the size of cards/the table (respectively) as they appear on your client.
