> To add a new contact into a secondary address book is clumsy and cumbersome (right click, properties, try to remember the email address you want to add..... 😱)
> Why not allow a simple drag and drop followed by a message "do you want to add <person name> to (address book name> option <yes> <cancel>
Sorry you are having difficulty.
A contact doesn't have a "properties" choice on right+click anywhere in the UI. And you haven't described your starting position, which could be either address book or message display.
In message display, a simple click on the star next to an address adds it to an address book. And a second click allows you to change the address book.
In Address Book you can click drag a contact from a source address book to a target address book, which copies the contact.
In both cases you don't need to remember an email address.
There is a third possibility, that you are talking about adding a contact to Mailing List. A Mailing List has properties.
It would help if you provided every step and location in the process, step by step.
