Changing Track Number In Library to #

I put tracks first, before title. But tracks are 1 or 2 digits, and there's a very large width and there's only a certain point that I can make it smaller. I think there should be a change from calling it "Track Number" to "#" I think people are smart enough to understand what it is if they want to use it. When you right click to add it it can still say Track Number just have it show as # in my library PLEASE.
