Preview adds my full name to all highlights and notes in pdf files. I'd rather have either my initials or nothing at all. This should be possible by going into Preview preferences -> pdf and either deselecting the checkbox where it says "add name to annotations" or changing the name in the text field. In my case, the checkbox is deselected by default, so there shouldn't be a name added to highlights. I tried checking the box and changing the name but that doesn't have any effect. Is there an explanation for this and another way of changing the author name?
