# TODO: On member role assign, welcome member using on_member_update
# TODO: Better help menu- AutoGen using <command>.help
# TODO: WaifuRater - Mention user and RNG a rating
# TODO: Admin tools - For commands already in and things like purge a chat
# TODO: Overwatch stats - Using Overwatch-API lib
# TODO: Move away from using ID's for everthing. Maybe replace list with dict
# TODO: Add check for no channel id when a module is enabled

# Fixed bug with blacklist remove options. So that any option not '+' or 'add' is no longer accepted as the remove option.
# Optimised removerole command
# New names for some commands so it is easier to know what module they change.
# Twitch Shilling
# Fixed major bug with the owner only commands
