I realize that the template editor has defined template tags and you can use HTML to edit them, but this is extremely cumbersome to someone who doesn't have time to learn HTML in order to make a professional-looking estimate message.

The estimate message tag/feature is something that is very valuable to me in my job, but due to its constraints, such as not holding onto any type of formatting (such as placing a space between paragraphs), it comes off looking very unprofessional to my clients sometimes. All I need is a working text box that holds onto the formatting once I save my progress.
