Makes multi-account and search do what they promise. From the unified inbox you can now move a message from a secondary account into that account's own folders, and a conversation no longer disappears from the unified view. Search leaves the Trash and Spam out of its results on every server, actually applies its advanced criteria (from, recipient, subject, attachment, date) instead of ignoring them, says honestly when it stopped short of the whole answer, shows contact photos, and its filters now slide in over the results like a drawer. The outbox keeps a reopened message safe: closing it puts it back in the queue instead of losing it, a failed send stays parked instead of restarting on its own, and an encrypted draft is never written in the clear. A self-hosted server whose certificate you signed with your own authority is reachable again. Also: a forwarded message is titled Forward, emptying the Trash reaches the server over IMAP too, push comes back on its own after a reboot or an update, and a mostly vertical arc scrolls the list instead of triggering a swipe.
