It's a good idea, but I think it looks butt ugly as it is now. The  
rows where I have no tab stops (just new line) don't colour at all,  
and no text on the lines with tabs colour either. I'd like the whole  
column as such coloured, if anything. I suppose this can't really be  
solved with scopes, but that's how I think it should look to be of  
any real help.
(not dissing your idea here, as I said, it's a good one, I just  
comment on the current state)
