AutoMinister is another great Excel application from Mike Mulka, creator of Automagic. It enables you to import XML files from all of your team's turns, and keep track on artefacts (lost and new ones each turn), characters, enemy characters, rumours from enemies (removing the rumours from your side for ease of reference), and much more. However, perhaps its best feature is the economic projection it offers.
