This is the sore thumb for communication with my group of friends. It is the reason that people go to alternative services (like Protonmail, mailbox.org, and Mykolab) or choose to continue using Gmail. I think that anyone who uses Tutanota for any kind of long-winded conversation will agree. Implementing this feature will give a major usability boost to Tutanota for teams of people.
