When you have a form that handles several different zones- and you want those zones divided visually, the divider is a quick and simple method to do that. However, it's such a light line it does get lost. Having the ability to use a thicker line, or different color would be extremely helpful.
Today, we use a Heading... with a fill... and spaces. This can take some time to tack down the perfect space count to get the perfect divider, LOL.
