Just updated the plugin to v0.0.9, this adds two additional features - "FulfillmentNotification" and "LoanReturn".

"FulfillmentNotification" is a request that ADE sends after you've successfully downloaded an eBook to let the Adobe server (and the server of the book distributor) know that the book has successfully been downloaded. This is not strictly necessary for the plugin to work (as, well, it's sent after you've already got the book), but it brings the behaviour of this plugin closer to the behaviour of ADE, so that should make it less likely that Adobe will detect and block this plugin.
If you do not want to send these fulfillment notifications, they can be disabled in the plugin settings. Though that will prevent loan returns (see below) from working.

"LoanReturn" is a request that ADE sends when you return a loaned book to the library. When you download an EPUB or PDF from a library using v0.0.9 or newer of this plugin, it will create a loan record in the plugin settings. In the plugin settings there's a new button "Show loaned books", which will show you a list of all books you got from a library (only where the loan period isn't over yet), and allows you to "return" the books to the library, just like the "return book" option in ADE would, so another person can get the book from the library.
Note that this does not remove the book file from Calibre - if you do not want to keep the returned book file you'll need to delete that yourself.

Additional note: If you're combining this plugin with DeDRM, there's nothing stopping you from immediately returning every book after the download so you can theoretically download infinitely many books from a library. I'd suggest not doing that, as Adobe (and your library) will know for how long you had each eBook, and I don't think that they'd like stuff like that.
