It basically displays all chat from a list of given chat channels and/or from a list of characters in big letters in the middle of the screen (the ones you see when you or the guild get a rank). It also plays a sound. Hard to miss important stuff that way.

It adds a command: /lissn , with four options:
/lissn channels -- List all available chanels
/lissn toggle CHANNEL -- enable/disable display for CHANNEL
/lissn boss CHARNAME -- display all chat from CHARNAME
/lissn bosses -- list all characters in the boss list

By default BATTLEGROUP chat is enabled
