It would also be good if the customer could manage their own addresses, including see what they've got saved as addresses in their account settings page.

Yes please!

Please make this one happen!!

Would love for this to be available as currently it's a waste of everyone's time to have to contact support to do it from their end each time.

It would be helpful if the could delete addresses too. If the customer could do it, we could log in as the customer to delete an address. Address changes are one of our biggest support issues. Not being able to reduce the clutter of old addresses is not great.

Yes please!
