I would like to suggest a couple of things for the JM:
1) Eliminate the escape option that mages have, because the infiltrators use that to sabotage the party and make us lose the JM.
2) Allow players to report someone by right clicking on them. Writing its nickname takes plenty of time. Even more so if you have to decipher between letters, numbers, uppercase and lowercase.
