For lower rank editors and those that tend to travel, it would be helpful to add a 1-3 pixel gradient border, likely at a 50% transparency level around each editing area based on the age of the area. I propose the gradient go from green to red for expiring edit areas and 50% grey for any LAM/AM areas for differentiation.

I know that it would be beneficial for me to have that visual representation as I patrol the EA in WME that I gain each Northern Hemisphere summer that I drive around the USA.
