Is there an existing addon that will simply remove the brackets that appear around player names? Also is there an easy way to enable class colouring in chat for all channels on all characters or is it a case of going through each one and manually switching it on? Been trying to work this one out for myself and failed so any help/advice would be much appreciated.
You can copy your entire chat setup (including class color preferences) by copying chat-cache.txt between characters' settings folders (inside the WTF folder). I don't know of any addons that only remove the brackets from player names, though.
