I have looked thru the settings and scripts, and have not been able to find this solution. I would like an address to be added automatically, anytime it's used, typed or received from, the 1st time. So, when I go to use the address again, it will 'auto-complete'.
ie: I send an email to an address that hasn't been used before, the next time I need to send one to that address, it will 'auto-complete' as I start to type it.
