My $0.02

Instead of using -F to denote filetypes, why not use colors? -G -- it 
shouldnt affect scripts at all, yet still provide the same sort of 
feedback. (Tho, I personally use csh's built-in "ls-F" instead of "ls", 
and actually tend to alias it to ls as well.)

Just a thought.

I do, however, like most of the other changes. Here's my stamp. 
"Approved" :)
