I'd like to have a way to easily see all the emails in the To:, CC:, etc. fields at once and to be able to copy them all at once.

In Apple's Mail.app, I just have to select the field to see the addresses and copy them. In Airmail, from what I can tell, I can only copy one email at a time from the down arrow by the from address. I also have a limited view of all the email addresses in each field which is problematic if there's a long list.

There are a few requests for copying addresses and doing so by right clicking. This is a more general request for streamlining viewing, copying and working with multiple email addresses.
