Regarding Auto loot setting: Master looter.
Jamba is setting the new master looter via CharacterName-RealmName, which is not an acceptable format for the /master command. If you manually type /master CharacterName-RealmName the client will redact it to CharacterName only, while you type it. Not sure how this is going to work with cross realm groups and same name characters.

My current work around is using IsBoxer to send the /master command with current slot character name only when I do group-leader/Jamba-master swaps. This requires two button pushes to set master looter due to the delay in changing the group leader.
