This looks similar to Topicbox (https://www.topicbox.com/ https://www.topicbox.com/) that Fastmail is building. Overall I think the current paradigm of mail clients is not the correct one: a MUA today is still a glorified view of individual emails, as if it was "just" a maildir viewer. I would rather have a HN- or Reddit-like view, where focus is put on the conversation rather than on the people. This will be more useful than focusing on folders (What's the use of a "Sent" folder ?)
