I was going through and fixing some symbol Line Spacing Factors on my symbols using the new feature added in the SE Beta and I thought, "It sure would be great if the Entity Properties Editor were persistent." I could then go around clicking on my symbols without having to go through the Ctrl+Right Click menu every time. It could also be useful in changing MText & PText factors when you have many to do.
