It would be great if we could configure Discord Chat to either ignore messages sent via other plugins or send them to specific Discord channels.
Example addition to config:
"Plugin Support" : {
     "BetterChat" : {
         "Exclude" : False,
         "Discord Channel" : "better-chat-log",
     "AdminChat": {
         "Exclude": False,
         "Discord Channel" : "admin-chat",
    }
}

Admin Chat supported has been added in the 0.13.0 Update.
