Add Volume and other fields to middle windows
I have a lot of commentary sets. The title of each book is the same but the volume number changes, perhaps by a number or by a subject. I use the volume field to record the identifier but can't seem to find a way to add the volume field to the middle window using the Firefox plugin.
I've been advocating allowing more (all?) fields to be added to the middle panel - best I can recall there's no compelling reason against that, it would just need to be done, but I could be wrong here.
