So, attached is something I knocked together based on the order of play included in the CAR. Let me know what you think! Can't promise its mistake-free! I'm also planning on making it a bit 'prettier' when I get some time but for now this will do.
It probably doesn't cover all expansions (I still need to include all the Robbers and Messengers indicators for example) but it covers most of the big ones.
I think there is potential for something useful here, particularly when playing with lots of expansions, or for those that don't know the game as well.
Cheers
