In SW:EoTE there are not a lot of things to keep track of or to hide from the players (well, that depends on how you run your campaigns). But this have all the things you need to know. Dice information, how to manage difficulties. So instead of shuffling the core rule book just take a quick look to your beautifully designed and printed screen and keep the flow of the game uninterrupted. It also feels sturdy, this may last for a few good years if treated with care.
