Boxes/squares around everything?

[Lucky]

Is there any way to disable the boxes around every character and creature? I realize it sounds weird, but I really don't like them.

Pressing "Shift+T" cycles through them. (Full, small and none, last I checked)

There's another, I think, to cycle backwards... But I can't remember what it might be.

A word of caution, though; it gets really hard to distinguish a Rare from a mob without those boxes...
