it already happened to me some times...
I have a book - maybe added it to the library a long time ago - which I read & rate it (I use the rating column as a read-flag too: unread books are zero-star).
Then some time after this I remember "... I read it not long ago... I gave it 4 stars ... which damn book is it???"
So: does calibre holds the date at which a book rating has changed?

thanks a lot for this incredible program!
