title_body: Is it possible to share annotations between a Kobo Glo and Calibre Viewer?
upvoted_answer: Apparently Calibre does already have the capability to capture the annotations from Kobo.
  
  When Kobo is attached to your computer, the "Send to Device" logo appears as a menu option in Calibre.  If you right click on that logo, the bottom menu option is "Fetch annotations (experimental)".  One caution however is that Calibre seems to fetch the annotations for ALL books that are on Kobo (rather than just the book that is currently highlighted), and then copies the annotations for each book on KOBO and appends it to the comments metadata of the corresponding book in Calibre.  All annotations are copied including any auto-generated bookmarks that identify how much of the book has been read on Kobo.
