Playing around with the *.Map.* api functions and came up with this.
Displays nearby resource nodes around the middle of the screen with icons matching what they are.
Fishing nodes show:
School of Fish = Quick Minnow
School of Clever Fish = Octopus
School of Rare Fish = Eel
Sunken Boat = Snowman (couldn't find a boat icon, and snowmen are cool!)
Rest of the resource types should show the icon of the raw resource.
Since the direction the player is facing isn't exposed to addons, it attempts to guess and rotates the display to match. It will get confused if you strafe or move backwards and will only update direction when moving. Can be disabled.
There's a crosshair in the middle of the display as a reference point. Can be disabled.
Toggles entire display on and off (default: on)
Toggles crosshair on and off (default: on)
Toggles display rotation (default: on)
Displays current icon size

Sets icon size to XX (range 10-100)
