Great. Oh, I should also mention, that test version (2 posts back from this) has another new feature I've been playing with:
You can drag and drop story urls, text containing story urls, or even emails (like from Thunderbird) containing story urls onto the FFDL plugin button. And drag and drop existing books in the library onto it for update.
It's very similar to how you d-n-d those onto the edit box in the Add dialog, but skips the step of opening the Add dialog first.
