@Jen23 - So is it working or not working for you?

I saw you posted but have removed a comment that you hadn't upgraded to the latest Calibre version. Can you confirm the version Calibre shows and the version of the plugin (there should be an About button on the plugin menu in the latest version).
@nightfool - thanks for the feedback. Its good to hear its working for you now
@jesscat - certainly there is the possibility, its a matter of finding time

I suppose I should figure out out to patch Calibre in addition to adding a plugin at some point...
