What key function does the Message Editor provide in comparison to the Message Viewer?

The Message Editor offers the critical function of allowing users to create new messages as well as edit existing ones before submission. This capability is essential because it enables users to modify content, format messages appropriately, and ensure accuracy before sending them. This editing capacity enhances communication by allowing for adjustments based on feedback or changing circumstances.

In contrast, the Message Viewer typically provides functionality focused on reviewing messages that have already been created and submitted, but it does not include the ability to modify those messages. The distinctions between the two tools highlight the importance of the Message Editor in the process of message creation and communication management.
