HandyNotes plugin for Hunters which shows Eagle Flight Network flight path locations on the world map.
This allows you to see if the Eagle Flight Network would be a faster way to get to a world quest, and also lets you know if the Flight Master's Whistle will take you to an Eagle Flight Network location (if it happens to be closer) instead of a regular location.
It uses the normal flight path winged boot icon, but tinted green. Hovering over it shows the name and zone of the flight path location.
There are options to include the icons on the minimap (hidden by default since normal flight paths aren't on the minimap) and to show the marker for the Trueshot Lodge eagle location (hidden by default due to clutter from the normal flight path marker).
