Addon for displaying location of museum pieces?
 

I found a thread that says to use map pins, but it must conflict with another addon because I only saw treasure chest pins. I was told destinations, but it doesn't seem to have an option for the vardenfell ancestor tombs.

Other options?

After installing the addon, did you open map and check off the filters? It works by adding options into the filters section of the map, so people can turn on/off whatever icons they need on the fly.
