Great if you don't need to ever edit icons

This was a great plugin until the url for one of my custom icons changed. There is no way to delete it and I added an icon with the same name which I thought should work, but instead it made two of the same icons, one with the right url and one with the wrong url. I’m even looking in PHPMYAdmin to see where this is stored to manually delete it and I can’t seem to find it. Being that the plugin hasn’t been updated in over 2 years and the forum questions go unanswered, I’m giving this a 1 star until someone adopts it and updates it.
