Hey everyone, new question:

Regarding the Calibre plugboards, I use one to add series name to the title of the books.

But how do I disable it without deleting it when I add books that aren't part of a series? Because series books usually give the correct series and number, but for books that aren't in a series, it looks like this in my ereader:

[]Aesop - Aesop's Fables

And tips? I've deleted the damn plugboard more times then I can count. :/
