Amazing work! Solved a number of things on my to do list
I don't know if the actual site adapter is the problem, but fimfiction.net doesn't split "My Little Pony" off into Category and the genre tags off into the Genre section.
And pardon me if this is a noob question
, but can the progress windows be placed inside the jobs section instead? I have a large list of fanfics now that I regularly check for updates, and I can't go off and do something else in Calibre until the metadata downloading is finished.
