Hello Jim
I sent you email about testing V1.1. If you didn't get it (spam filter issue probably), PM me to let me know.
I also made some suggestions that I will copy below, so they are available for criticism by others.

Suggestion: my wife is currently reading a long book, New York, by Edward Rutherfurd, that fails to paginate. I have tried all the obvious things to make more memory available, to no avail. If pagination fails, is it reasonable to paginate the chapter (using the TOC to define chapters) and provide page numbers for that? Or if not the chapter, perhaps the EPUB segment? In this latter case, one would need all of the segment number, the current page number, and the last page number.
And as long as I am here

-- in V1.0 the value of the checkbox 'Search Subfolders in Library' is not saved. Result: the library is empty next time one goes back to it. I am working around this by using Calibre to put the titles in one directory, but that has its own problems, such as very long file names and overly-large directories.
