I think something like this would be a very good idea. I almost 
always use "none" for the display mode when"viewing" a large set. In

needed a "none" mode because things were so slow. He added it almost 
immediately.  The "none" mode would still be useful as it compresses 
output but most people want to see the problems (not just file names) 
so speeding things up would be a great help.
