In music theory class, we use roman numerals in place of numbers. Major is Upper case (like 'V') and minor lower case ('v'). This also allows to specify 6 and 7 chords if you want to. You also don't have to traspose minor. Other than that, the rest of the symbols are the same. It's a new way of using them though.
I've never really thought in terms of notes when I'm playing music, but in terms of intervals. If I know what the tonic is, I know where the other tones are. I think about where they are in relation to the tonic as apposed to what letter you call them.
Thanks for sharing this Rick. Your right that it isn't flawless (notating music never is) but it's a good system.
