A function I am longing for in Cardbook
If you right click on the senders address in an incoming email, you can "add to cardbook" when it is a new address. This is great.
If you already have the address, you can edit the address. This is also great.
But if you have the address in two maps (address books), you can only edit the address in the first map (alphabetically ordered), not the second. That's a pity.
If you would like to add an existing address to a second map(address book), that is not possible because you only find 'edit'. That is also a pity.
Greatful for the great tool that should replace the standard addressbook in Thunderbird.
