The old "Query Internet" function has been renamed to "Download from Internet".

The "download" window has been redesigned.

You now edit the downloaded data in a separate window (similar to how to edit books from the Book View):

In addition, there is a new option called "Mark books before transfer". When this is selected, the program will first unmark all existing books, then mark the newly transferred books and only show these books (the subset) when you choose Transfer.
