I have downloaded a few books that do not have any information on the title for the author. Which makes management of my books more difficult. I also have a number of books that are part of a series, but the title does not show which number they are. It would be very useful to be able to amend the details.
I create a pdf of the reading order, using WordPad on my Laptop and use the Personal Document Service to send that to my Kindle. I put the pdf in the Collection for the Series and refer to that if I need to know book is next. It's not an elegant solution but it works well for me.
