Address Validation would be a great enhancement. Since we exclusively use UPS, UPS offers businesses like ours a free tool that does street-level address validation. However, because of the licensing, this can't just be "Added in" for all users; you have to have the license from UPS.

It would be very nice if there were a "hook" to use that validation if it is available to you.

I can get more information for you if necessary.
