Please allow users to compose their message before entering an address. This would require showing the composition box/area when one first clicks to start a message.

Sometimes it is useful to write first, quickly when something comes to mind. Right now, users have to stop and find or type a contact name(s) before composing. This can break the train of thought.

Writing first also adds a type of security. If the address box is empty, it doesn't matter if one inadvertently presses the send button before the message is ready to send.

Thanks,
