i see that Humminbird (finally) released the new Waypoint Management system with the recent software updates.

among a number of updates that make using and editing waypoints easier such as editing multiple waypoints at once, grouping waypoints, and different waypoint categories, they also included a way to set the default icon to anything you want. so now i can lay down 20 weedline icons without having to manually edit every one to make it look like a weed instead of a blue dot. (why anyone would want to do that is the subject for another thread!)  Lowrance has had this feature forever, and it's good to see Humminbird finally including that ability.
