This is really neat! However, may I offer a suggestion?
I personally think it would be great if we could change the order of the components. For example, it makes more sense to me to specify the fandom before the author, and the characters before the rating.
I realize I can simply change the order once it's pasted but it kind of defeats the purpose of the script if I do that :p

I don't want to rain on your parade, I seriously couldn't believe it when I saw that it's just so handy, but just thought I'd add my two cents :)
