I saw in some images from other platforms it can take up alot of space.
Made the boxed horizontal, rather than vertical.
WIP Remade reveal zone
+ darkened card area to eaisily see boundries
+ reverted back to using a window
+ window can be resized
+ removed fake title bar and "X"
+ moved all cards revealed slightly to the right, makes it easier to
drag-select from the left
Cleanup
Changed style to use cockatrice icon
Changed cast
from static_cast to qstyleoption_cast
