The compose screen is nicer to use. Tapping anywhere below the header now places the cursor in the message, which scrolls as you write. Recipient and attachment lists no longer grow without limit: each scrolls on its own, and a recipient field folds to a short "+N" summary once you move on. The keyboard no longer pushes the header off-screen, field separators run edge to edge with a subtly tinted header, and the fields keep accessible tap targets.
