Nice! 👍

Only thing is I see an error in the owncloud.log:

Argument 1 passed to OCA\\Mail\\Model\\IMAPMessage::hordeToAssoc()
must be an instance of Horde_Mail_Rfc822_Address, instance of Horde_Mail_Rfc822_Group given,
called in \/home\/jan\/owncloud\/apps\/mail\/lib\/model\/convertaddresses.php
on line 73
and defined at \/home\/jan\/owncloud\/apps\/mail\/lib\/model\/convertaddresses.php#33"

Also if we do lazy loading, we can remove the button from the bottom there and replace it with just a large centered spinner directly in the list.
