Nice app but it really needs to allow the user to select the lights of interest before it displays. As noted in a different thread it has a display limit of 500 points and you need to zoom in pretty tight to see anything pop up in some places, like the Great Lakes, due to huge number of lights that are in the populated list.

The legend should show the color coded lights and allow the user to toggle each light type as a layer so that they can identify specific points of interest.

It is functionally unusable in some areas due to the huge number of navigational buoys, etc along inland rivers and it apparently has a problem determining window extents and centering the display on the user's area of interest. If you display the entire Great Lakes region you will find that your displayed lights are along a couple of rivers in the lower left with nothing in the center of the display. If you shuffle to the north a bit and zoom another notch it suddenly fills the lower right corner, still with nothing in the center of the display.

Filtering by type of light would solve a lot of that if you keep the 500 point limit.

I understand that it took a lot to get this far. You are close to having a great app that I would be comfortable recommending to a friend who travels specifically to visit lighthouses. This is not that app yet but it could be.

Great work. Take that next step.
