Yes, I also assign each pin a meaningful name - RawVoltIn, and stuff like that. The only place I had to remember the uC pins vs Arduino pins is in the very first part of sketch where they are assigned. Once that is done, I never refer to the uC/Arduino pin number again, only the meaningful name. That way it's not such a "big" deal, just felt it would be nice.
Thanks to all for suggestions and ideas.
