@tilia - I think the last time you edited the configuration for the lists in that other library must have been a much older version of the plugin. I have added some changes in to make sure others will not get the same error, thanks.

@capnm - I have fixed the disabled checkbox bug. I also found a few bugs to do with remove lists. It is fairly complex in there now, because at the time I produce the auto-sync list I don't "actually" know what is on the device (since the sending of books to the device is a background job), instead it is "estimated" based on all the list actions you have applied. Let me know how you get on with this version.

Thanks for the feedback to both of you, just the sort of stuff I wanted.
