Works flawlessly with Lightning 0.9, very useful. Does not work with Lightning Inverse 0.9.7. If you already installed the Inverse edition and get an error at startup, then you will find ThunderBirthday deactivated and your birthday calendar vanished. Re-install 0.9 again, and your birthday calendar will reappear. If you prefer to stay with Lightning 0.9.7, remove your birthday addressbook first and then install 0.9.7 again.
