Fix Problem in Using IME inside Search Box

When entering Japanese (or some other language) in Fastmail's search input, using the IME to enter text requires pressing the Enter key before completing the input. Fastmail's Web UI performs the search at the moment the Enter key is hit even though the search string is completed. Fastmail Plus fixes this problem.

Fold the "reply-to" part of messages (when the message's div has an id containing appendonsend)

Maximize Reading-pane Width
