Any addons that do this? I would like to detach the "say" box were you enter text from the chat box and relocate it.

prat 3 does it, there is a dropdown option to make the box 'floating' (i think thats the right term) and then u can move it around, I have mine centered and thigh level w/ my toon. I love it. You can also texture it, i recomend xperl texture, the acheivement one seems broken btw.
