Some small changes have been made to how Kobo Highlights works under the hood:
* It will now keep track of previously imported bookmarks in a hidden JSON file instead of trying to parse the markdown files. The JSON file is stored in the same directory as the markdown files.
* The author information is now retrieved directly from the SQLite database. Previously Kobo Highlights assumed that the files in the ereader followed the file structure used by [Calibre](https://calibre-ebook.com/). According to that file structure each ebook file is placed in a directory named after the book author. This was a fragile approach since the file structure was not enforced unless Calibre was used exclusively to manage the ebooks.
