I don't know about such an addon but you could try this addon here:
http://www.esoui.com/downloads/info6...tTabBrain.html
It will provide you keybindings to minimze the chat and cycle your chat tabs left + right (or choose a specific chat tab) by keybindings.
The chat will be maximized again if you use the keybindings.
In addition another addon, this here:

It will generate some sounds if someones writes your name or specific key words, or your guilds are writing, a friend is writing etc.
Maybe this helps for the moment.
