This feature started here - thanks to everyone who shared their thoughts over in this thread:
The basic idea of it is that you can go to your LifeMap page, and click the magnifying glass button in the map controls. This will place markers down on the map for all your uncompleted Nodes in view.
Pair this with LifeMap Live, and you’re unstoppable!
There is a lot of potential for this feature, and this is just the start!
