I was wondering where the suggestions come from when typing something into a property field (tags, authors, etc.). For example, when typing in a tag for a picture, a menu of suggestions show up with check boxes to choose them. I'm guessing some come from previously entered information from other files, including music because Britney Spears keeps showing up. But not all entered information is added. There are many things I have typed in several times and they don't show up in the list. Is there a way to edit these and how do they come about?
