I just bought a Kobo (previously using old Kindle Paperwhite) and discovered this great plugin. Thanks so much for providing such useful functionality! I'm struggling a little to understand exactly how it works with respect to date last read, and was hoping someone could clarify. I have side-loaded about 300 books from calibre onto the Kobo, and in calibre about half of them already have a "last read" date set. I have configured the Kobo Utilities plugin to use that column. I manually updated the percent read column to 100% and the reading status on the Kobo to Finished using this plugin. Now when I plug in the Kobo, I get the expected box up saying it's queuing books to update reading position. Then when I get the list of books, in addition to the ones I've actually been reading, it seems to also give me the list of books I've already read, with the indication that it wants to change the date read from its existing value (correct) to a new value of blank. What am I doing wrong? I'd like to keep my existing date read values. All help gratefully received.
