When out running I usually take a look at the mobile map to chek my current position and display the nodes. It would be nice if the current position could also display a 25m diameter circle around it (if I recall correctly that’s the maximum distance you have to be near a node to capture it) so you can check on the spot if you are close enough to get the node.
Also, when clicking on a node in the node hunter that 25m circle could also be toggled, so if you intend to capture a hard to get one it you can see possible points in the map where you could go to get it.
