Plugin Idea: kindle.amazon.com integration
It would be great if it were possible to sync (or simply upload) book entries with star ratings to the kindle.amazon.com service.
e.g. create a book entry with a star rating and tagged "read" on kindle.amazon.com.
It would certainly encourage me to use the star ratings system in Calibre! Otherwise I'm just maintaining multiple databases.
I hope somebody would like to make this plugin.
