When I first started playing with Calibre a week or two back, I was certain that when I already had Tags entered for a book, and then downloaded social content etc, that the new tags were ADDED to my own initially entered tags.

Since the last update (?) I've been finding that when I download social content, my original tags (usually something like UNREAD) are replaced by the new content.

I'm trying to figure out which of the following is correct:

a) did I flip a switch somewhere?
b) did this change during an update (intentionally or unintentionally)
c) it has always been this way, and I'm just misremembering.

Thanks for helping me figure it out...
