Many of the Logos maps have great information and images, such as arrows in the map below. However, there are times when I'd like to see the same map with just the place names and not the arrows and such. I have another Bible app with a map that lets you toggle on/off both ancient and modern boundary lines and place names. Those maps are very small and not nearly as colorful as Logos maps but it is nice to be able to apply overlays so you show or hide information as you want.
