Thanks once again for a fantastic product!
Could you please explain how to use the feature "User Categories?" I have a user category defined in Calibre and was trying to use it with Calibre Companion. Are "User Categories" the same as Calibre's "Add your own column?" I have a column defined as read and it is of type Yes/No. I defined it in Calibre Companion as #read:no. It returns a blank screen. What am I doing wrong?
